DT-based mv643xx_eth probes and creates platform_devices for the

Sebastian Hesselbarth f564412c93 net: mv643xx_eth: fix orphaned statistics timer crash
The periodic statistics timer gets started at port _probe() time, but
is stopped on _stop() only. In a modular environment, this can cause
the timer to access already deallocated memory, if the module is unloaded
without starting the eth device. To fix this, we add the timer right
before the port is started, instead of at _probe() time.

Sebastian Hesselbarth 041b4ddb84 net: mv643xx_eth: update statistics timer from timer context only
Each port driver installs a periodic timer to update port statistics
by calling mib_counters_update. As mib_counters_update is also called
from non-timer context, we should not reschedule the timer there but
rather move it to timer-only context.

Andi Kleen 58e4e1f6ca igb: Avoid uninitialized advertised variable in eee_set_cur
eee_get_cur assumes that the output data is already zeroed. It can
read-modify-write the advertised field:

              if (ipcnfg & E1000_IPCNFG_EEE_100M_AN)
2594			edata->advertised |= ADVERTISED_100baseT_Full;

This is ok for the normal ethtool eee_get call, which always
zeroes the input data before.

But eee_set_cur also calls eee_get_cur and it did not zero the input
field. Later on it then compares agsinst the field, which can contain partial
stack garbage.

Zero the input field in eee_set_cur() too.

Rob Herring 0cf2f38007 net: calxedaxgmac: determine number of address filters at runtime
Highbank and Midway xgmac h/w have different number of MAC address filter
registers with 7 and 31, respectively. Highbank has been wrong, so fix it
and detect the number of filter registers at run-time. Unfortunately,
the version register is the same on both SOCs, so simply test if write to
the last filter register will take a value. It always reads as 0 if not.

In commit 2ee68f621a (net: calxedaxgmac: fix various errors in

However, the loop to zero out the entries failed to increment the register
address resulting in only 1 entry getting cleared. Fix this to correctly
use the loop index. Also, the end of the loop condition was off by 1 and
should have been <= rather than <.

Hauke Mehrtens ead2402cb4 tg3: add support a phy at an address different than 01
When phylib was in use tg3 only searched at address 01 on the mdio
bus and did not work with any other address. On the BCM4705 SoCs the
switch is connected as a PHY behind the MAC driven by tg3 and it is at
PHY address 30 in most cases. This is a preparation patch to allow
support for such switches.

phy_addr is set to TG3_PHY_MII_ADDR for all devices, which are using
phylib, so this should not change any behavior.

This patch renames the LL_EXTENDED_STATS and some of the functions required to
implement busy polling in the ixgbe driver, in order to remove the marketing
"low latency" blurb which hides what the code actually does.

This furthers work which was requested by Linus Torvalds when the initial busy
poll code was included in the kernel. The code in the ixgbe driver itself was
never properly renamed to reflect the change to busy polling as the title.

Ariel Elior 9a8130bc38 bnx2x: Don't disable/enable SR-IOV when loading
Current bnx2x implementation controls the number of VFs only by
standard sysfs support, and will reject setting the number of VFs
when the PF is not loaded.
As a result, there is no need to schedule a delayed work to enable
SR-IOV when PF is loaded, as the number of VFs at that point
must be 0.

Mugunthan V N 5892cd135e drivers: net: cpsw-phy-sel: Add new driver for phy mode selection for cpsw
The cpsw currently lacks code to properly set up the hardware interface
mode on AM33xx. Other platforms might be equally affected.

Usually, the bootloader will configure the control module register, so
probably that's why such support wasn't needed in the past. In suspend
mode though, this register is modified, and so it needs reprogramming
after resume.

This patch adds a new driver in which hardware interface can configure
correct register bits when the slave is opened.

The AM33xx also has a bit for each slave to configure the RMII reference
clock direction. Setting it is now supported by a per-slave DT property.

This code path introducted by this patch is currently exclusive for
am33xx and same can be extened to various platforms via the DT compatibility
property.

Mikulas Patocka 3361dc9538 skge: fix invalid value passed to pci_unmap_sigle
In my patch c194992cbe ("skge: fix
broken driver") I didn't fix the skge bug correctly. The value of the
new mapping (not old) was passed to pci_unmap_single.

If we enable CONFIG_DMA_API_DEBUG, it results in this warning:
WARNING: CPU: 0 PID: 0 at lib/dma-debug.c:986 check_sync+0x4c4/0x580()
skge 0000:02:07.0: DMA-API: device driver tries to sync DMA memory it has
not allocated [device address=0x000000023a0096c0] [size=1536 bytes]

This patch makes the skge driver pass the correct value to
pci_unmap_single and fixes the warning. It copies the old descriptor to
on-stack variable "ee" and unmaps it if mapping of the new descriptor
succeeded.

This patch should be backported to 3.11-stable.

Ariel Elior cbbf77de64 bnx2x: handle known but unsupported VF messages
Commit b9871bcf "bnx2x: VF RSS support - PF side" has deprecated one of
the previous existing messages. If an old VF driver were to send this message
to the PF then the PF will not reply and leave the mailbox in an unsteady
state (and cause a timeout on the VF side).

Wait until firmware ack is written before unlocking channel

Yuval Mintz 0a5ccb759d bnx2x: prevent masked MCP parities from appearing
During flows which mask block attentions (e.g., register dump) all parities
are masked. However, unlike other blocks the MCP's attention is not masked
inside the block but rather the indication to the driver. If another attention
(e.g., link change) will occour while there's an MCP parity, the driver will
ignore the fact that the parity is masked and erroneously report a parity.

This patch forces the driver to read the MCP masking while checking for
parities.

Yaniv Rosner b6a9c1ef3d bnx2x: Generalize KR work-around
Previously, in case of KR link down, the driver would reset the PHY and restart
auto negotiation only when old Warpcore microcode was used (below D108).
This patch comes to generalize this by keep trying to restart KR link,
regardless of Warpcore microcode, since it was found that it solves another link
issue which source is a link-partner. As part of this change, the signal
detect is no longer a condition to apply the work-around to cover this new case.
Like before, as long as the link is down, AN will be restarted every 2 seconds.

The fallback to 32-bit DMA mask is rather odd:
	if (!dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)) &&
	    !dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))) {
		pci_using_dac = 1;
	} else {
		err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32));
		if (err) {
			err = dma_set_coherent_mask(&pdev->dev,
						    DMA_BIT_MASK(32));
			if (err) {
				dev_err(&pdev->dev, "No usable DMA "
					"configuration, aborting\n");
				goto err_dma;
			}
		}
		pci_using_dac = 0;
	}
This means we only set the coherent DMA mask in the fallback path if
the DMA mask set failed, which is silly.  This fixes it to set the
coherent DMA mask only if dma_set_mask() succeeded, and to error out
if either fails.

Ben Hutchings 183233bec8 sfc: Allocate and link PIO buffers; map them with write-combining
Try to allocate a segment of PIO buffer to each TX channel.  If
allocation fails, log an error but continue.

PIO buffers must be mapped separately from the NIC registers, with
write-combining enabled.  Where the host page size is 4K, we could
potentially map each VI's registers and PIO buffer separately.
However, this would add significant complexity, and we also need to
support architectures such as POWER which have a greater page size.
So make a single contiguous write-combining mapping after the
uncacheable mapping, aligned to the host page size, and link PIO
buffers there.  Where necessary, allocate additional VIs within
the write-combining mapping purely for access to PIO buffers.

Link all TX buffers to TX queues and the additional VIs in
efx_ef10_dimension_resources() and in efx_ef10_init_nic() after
an MC reboot.

Segmentation remains in the driver, but we generate option descriptors

Reduce tso_state::ipv4_id to 16 bits, so it doesn't overflow into the

Daniel Pieczko dfdaa95c7a sfc: Wait for MC reboot to complete before scheduling driver reset
Scheduling a reset following an MC reboot event before waiting for
reboot to complete results in a race that can lead to a state where
must_realloc_vis is false in efx_ef10_fini_dmaq() but the VIs have
been destroyed during the MC reboot.

To avoid MC errors when trying to remove VIs that do not exist, wait

Mikulas Patocka c194992cbe skge: fix broken driver
The patch 136d8f377e broke the skge driver.
Note this part of the patch:
+               if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) {
+                       dev_kfree_skb(nskb);
+                       goto resubmit;
+               }
+
                pci_unmap_single(skge->hw->pdev,
                                 dma_unmap_addr(e, mapaddr),
                                 dma_unmap_len(e, maplen),
                                 PCI_DMA_FROMDEVICE);
                skb = e->skb;
                prefetch(skb->data);
-               skge_rx_setup(skge, e, nskb, skge->rx_buf_size);

The function skge_rx_setup modifies e->skb to point to the new skb. Thus,
after this change, the new buffer, not the old, is returned to the
networking stack.

This bug is present in kernels 3.11, 3.11.1 and 3.12-rc1. The patch should
be queued for 3.11-stable.

Michael Chan 48a3056973 cnic: Fix crash in cnic_bnx2x_service_kcq()
commit 104a43edb2
    cnic: Use CHIP_NUM macros from bnx2x.h

changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE
is supported or not.  There is another place in cnic that is still using
the old method to determine if FCoE is supported or not.  The 2 methods
may not yield the same result after the network interface is brought down
and up.  This will cause the crash as cnic_bnx2x_service_kcq() will access
the uninitialized cp->kcq2.

The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which
uses the bnx2x NO_FCOE() macro.  As a follow-up, we can clean up the code
to remove the old method as it is no longer needed.

Russell King 3e5480791e DMA-API: net: brocade/bna/bnad.c: fix 32-bit DMA mask handling
The fallback to 32-bit DMA mask is rather odd:
	if (!dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)) &&
	    !dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))) {
		*using_dac = true;
	} else {
		err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32));
		if (err) {
			err = dma_set_coherent_mask(&pdev->dev,
						    DMA_BIT_MASK(32));
			if (err)
				goto release_regions;
		}

This means we only try and set the coherent DMA mask if we failed to
set a 32-bit DMA mask, and only if both fail do we fail the driver.
Adjust this so that if either setting fails, we fail the driver - and
thereby end up properly setting both the DMA mask and the coherent
DMA mask in the fallback case.

This is important patch for new devices that support unaligned
addressing. That devices suffer from the backward-compatibility bug in
DMA engine. In theory we should be able to use old mechanism, but in
practice DMA address seems to be randomly copied into status register
when hardware reaches end of a ring. This breaks reading slot number
from status register and we can't use DMA anymore.

have the appropriate bitmasks for R/W and RO bits for affected parts.

Shawn Rader gets credit for finding and fixing the register overrun.

Emil Tantilov 0f8fdab133 ixgbe: fix ethtool reporting of supported links for SFP modules
This patch resolves an issue where the driver will display incorrect info
for Q/SFP+ modules that were inserted after the driver has been loaded.

This patch adds a call to identify_phy() in ixgbe_get_settings() prior to
calling get_link_capabilities() which needs the PHY data in order to
determine the correct settings.

Maciej W. Rozycki 5359b938c0 MIPS: DECstation I/O ASIC DMA interrupt handling fix
This change complements commit d0da7c002f7b2a93582187a9e3f73891a01d8ee4
and brings clear_ioasic_irq back, renaming it to clear_ioasic_dma_irq at
the same time, to make I/O ASIC DMA interrupts functional.

Unlike ordinary I/O ASIC interrupts DMA interrupts need to be deasserted
by software by writing 0 to the respective bit in I/O ASIC's System
Interrupt Register (SIR), similarly to how CP0.Cause.IP0 and CP0.Cause.IP1
bits are handled in the CPU (the difference is SIR DMA interrupt bits are
R/W0C so there's no need for an RMW cycle).  Otherwise the handler is
reentered over and over again.

The only current user is the DEC LANCE Ethernet driver and its extremely
uncommon DMA memory error handler that does not care when exactly the
interrupt is cleared.  Anticipating the use of DMA interrupts by the Zilog
SCC driver this change however exports clear_ioasic_dma_irq for device
drivers to choose the right application-specific sequence to clear the
request explicitly rather than calling it implicitly in the .irq_eoi
handler of `struct irq_chip'.  Previously these interrupts were cleared in
the .end handler of the said structure, before it was removed.

====================
Intel Wired LAN Driver Updates

This series implements the new i40e driver for Intel's upcoming
Intel(R) Ethernet Controller XL710 Family of devices.

V7: many changes from a few comments:
    use linux errno types
    change I40E_SUCCESS to 0, standardize returns
    change s32 return values to int
    use void return values where possible
    prefer use of int over i40e_status
V6: rename Kbuild to Makefile
    rename i40e_mem[set|cpy] to regular memset/memcpy
V5: remove sysfs support from this set, will rearchitect
    changes from community comments
V4: addresses remaining community comments, mostly trivial edits.
    major sparse based cleanup of possible endian issues
    removal of most of __func__ references
    sizeof(*var) instead of sizeof(struct ...)
    change 'NULL ==' tests to !NULL
    implement xps
    use kernel bitshift macros (upper_32_bits, etc)
V3: many more individual comments addressed, thanks reviewers!  Many
    other changes due to internal review and development.
V2: each patch has individual comments, in general, feedback from the
    list was applied and addressed. Many changes due to internal review
    and coding as well.
V1: initial send

Let me start by saying thanks and we appreciate any time spent by
those of you who review and comment on this new driver, and we will
attempt to address and respond to all issues brought to our attention.

I tried to break the patches up to ease review, but the series should
apply and still be bisectable, as the last patch adds the driver to
the kernel compile with CONFIG_I40E.

This driver is for a brand new bit of silicon that has a different
design than other Intel Ethernet silicon, and therefore needed a new
driver.

The hardware has quite a bit of capability and this driver is only
meant to provide basic functionality at first.  Future patches will
continue to add functionality and bug fixes.

This initial release is very early in the product cycle with the intent
of getting initial support into the kernel before users have the
hardware available to purchase.  A software development manual is not
ready yet but will be available when the hardware ships.

The driver development model and interaction with community submitted
patches *will not be any different* than what we are currently doing
today.  We plan to continue established processes.

An associated i40evf driver has been posted for review.

List of tools we ran in preparation:
way more sparse clean
make W=1, W=2 clean
checkpatch (almost) clean
        total: 1 errors, 4 warnings, 30461 lines checked
        NOTE: Ignored message types: LONG_LINE
        - issues have been addressed and the remainders
          are noise.
codespell clean
smatch (almost) clean with a couple minor warnings
coccicheck clean
namespacecheck clean
allmodconfig clean
ppc64 build clean (untested)

This driver is a team effort, thank you to Joseph Gasparakis,
Shannon Nelson, Anjali Singhai-Jain, Mitch Williams, Neerav
Parikh, Vasu Dev, Kavindya Deegala, Yi Zou, and PJ Waskiewicz.

Michal Schmidt 996dedbafe bnx2x: avoid atomic allocations during initialization
During initialization bnx2x allocates significant amounts of memory
(for rx data, rx SGEs, TPA pool) using atomic allocations.

I received a report where bnx2x failed to allocate SGEs and it had
to fall back to TPA-less operation.

Let's use GFP_KERNEL allocations during initialization, which runs
in process context. Add gfp_t parameters to functions that are used
both in initialization and in the receive path.

Use an unlikely branch in bnx2x_frag_alloc() to avoid atomic allocation
by netdev_alloc_frag(). The branch is taken several thousands of times
during initialization, but then never more. Note that fp->rx_frag_size
is never greater than PAGE_SIZE, so __get_free_page() can be used here.

This patch proposes to remove the MLX5_DEBUG kernel configuration
parameter defined in drivers/net/ethernet/mellanox/mlx5/core/Kconfig,
but used nowhere in the makefiles and source code.

This could also be fixed by using this parameter,
but this may be a leftover from driver development...

Thomas Petazzoni 7140860291 net: mvneta: properly disable HW PHY polling and ensure adjust_link() works
This commit fixes a long-standing bug that has been reported by many
users: on some Armada 370 platforms, only the network interface that
has been used in U-Boot to tftp the kernel works properly in
Linux. The other network interfaces can see a 'link up', but are
unable to transmit data. The reports were generally made on the Armada
370-based Mirabox, but have also been given on the Armada 370-RD
board.

The network MAC in the Armada 370/XP (supported by the mvneta driver
in Linux) has a functionality that allows it to continuously poll the
PHY and directly update the MAC configuration accordingly (speed,
duplex, etc.). The very first versions of the driver submitted for
review were using this hardware mechanism, but due to this, the driver
was not integrated with the kernel phylib. Following reviews, the
driver was changed to use the phylib, and therefore a software based
polling. In software based polling, Linux regularly talks to the PHY
over the MDIO bus, and sees if the link status has changed. If it's
the case then the adjust_link() callback of the driver is called to
update the MAC configuration accordingly.

However, it turns out that the adjust_link() callback was not
configuring the hardware in a completely correct way: while it was
setting the speed and duplex bits correctly, it wasn't telling the
hardware to actually take into account those bits rather than what the
hardware-based PHY polling mechanism has concluded. So, in fact the
adjust_link() callback was basically a no-op.

However, the network happened to be working because on the network
interfaces used by U-Boot for tftp on Armada 370 platforms because the
hardware PHY polling was enabled by the bootloader, and left enabled
by Linux. However, the second network interface not used for tftp (or
both network interfaces if the kernel is loaded from USB, NAND or SD
card) didn't had the hardware PHY polling enabled.

This patch fixes this situation by:

 (1) Making sure that the hardware PHY polling is disabled by clearing
     the MVNETA_PHY_POLLING_ENABLE bit in the MVNETA_UNIT_CONTROL
     register in the driver ->probe() function.

 (2) Making sure that the duplex and speed selections made by the
     adjust_link() callback are taken into account by clearing the
     MVNETA_GMAC_AN_SPEED_EN and MVNETA_GMAC_AN_DUPLEX_EN bits in the
     MVNETA_GMAC_AUTONEG_CONFIG register.

This patch has been tested on Armada 370 Mirabox, and now both network
interfaces are usable after boot.

  Marvell Armada 370/XP network unit") ]

Vineet Gupta 27082ee1b9 ethernet/arc/arc_emac: Fix huge delays in large file copies
copying large files to a NFS mounted host was taking absurdly large
time.

Turns out that TX BD reclaim had a sublte bug.

Loop starts off from @txbd_dirty cursor and stops when it hits a BD
still in use by controller. However when it stops it needs to keep the
cursor at that very BD to resume scanning in next iteration. However it
was erroneously incrementing the cursor, causing the next scan(s) to
fail too, unless the BD chain was completely drained out.

Michal Schmidt df95fc44c0 qlcnic: use standard NAPI weights
Since commit 82dc3c63 ("net: introduce NAPI_POLL_WEIGHT")
netif_napi_add() produces an error message if a NAPI poll weight
greater than 64 is requested.

qlcnic requests the weight as large as 256 for some of its rings, and
smaller values for other rings. For instance in qlcnic_82xx_napi_add()
I think the intention was to give the tx+rx ring a bigger weight than
to rx-only rings, but it's actually doing the opposite. So I'm assuming
the weights do not really matter much.

Just use the standard NAPI weights for all rings.

  This has been sitting in linux-next for a whole cycle"

[ There are still some PTR_RET users scattered about, with some of them
  possibly being new, but most of them existing in Rusty's tree too.  We
  have that

Sergei Shtylyov d2779e9946 sh_eth: fix napi_{en|dis}able() calls racing against interrupts
While implementing NAPI for the driver, I overlooked the race conditions where
interrupt  handler might have called napi_schedule_prep() before napi_enable()
was called or after napi_disable() was called. If RX interrupt happens, this
would cause the endless interrupts and messages like:

sh-eth eth0: ignoring interrupt, status 0x00040000, mask 0x01ff009f.

The interrupt wouldn't even be masked by the kernel eventually since the handler
would return IRQ_HANDLED all the time.

As a fix, move napi_enable() call before request_irq() call and napi_disable()
call after free_irq() call.

Duan Fugang-B38611 36e24e2ee2 net: fec: fix the error to get the previous BD entry
Bug: error to get the previous BD entry. When the current BD
is the first BD, the previous BD entry must be the last BD,
not "bdp - 1" in current logic.

V4:
  * Optimize fec_enet_get_nextdesc() for code clean.
    Replace "ex_new_bd - ring_size" with "ex_base".
    Replace "new_bd - ring_size" with "base".

V3:
  * Restore the API name because David suggest to use fec_enet_
    prefix for all function in fec driver.
    So, change next_bd() -> fec_enet_get_nextdesc()
        change pre_bd()  -> fec_enet_get_prevdesc()
  * Reduce the two APIs parameters for easy to call.

V2:
  * Add tx_ring_size and rx_ring_size to struct fec_enet_private.
  * Replace api fec_enet_get_nextdesc() with next_bd().
    Replace api fec_enet_get_prevdesc() with pre_bd().

  * Move all ring size check logic to next_bd() and pre_bd(), which
    simplifies the code redundancy.

V1:
  * Add BD ring size check to get the previous BD entry in correctly.

Rob Herring 2ee68f621a net: calxedaxgmac: fix various errors in xgmac_set_rx_mode
Fix xgmac_set_rx_mode to handle several conditions that were not handled
correctly as Lennert Buytenhek describes:

If we have, say, 100 unicast addresses, and 5 multicast addresses, the
unicast address count check will evaluate to true, and set use_hash to
true.  The multicast address check will however evaluate to false, and
use_hash won't be set to true again, and XGMAC_FRAME_FILTER_HMC won't
be OR'd into XGMAC_FRAME_FILTER, but since use_hash was still true
from the unicast check, netdev_for_each_mc_addr() will program the
multicast addresses into the hash table instead of using the MAC
address registers, but since the HMC bit wasn't set, the hash table
won't be checked for multicast addresses on receive, and we'll stop
receiving multicast packets entirely.

Also, there is no code that zeroes out MAC address registers reg..31
at the end of this function, meaning that under the right conditions,
unicast/multicast addresses that were previously in the filter but
were then deleted won't be cleared out.

Rob Herring cbe157b60c net: calxedaxgmac: fix race with tx queue stop/wake
Since the xgmac transmit start and completion work locklessly, it is
possible for xgmac_xmit to stop the tx queue after the xgmac_tx_complete
has run resulting in the tx queue never being woken up. Fix this by
ensuring that ring buffer index updates are visible and recheck the ring
space after stopping the queue. Also fix an off-by-one bug where we need
to stop the queue when the ring buffer space is equal to MAX_SKB_FRAGS.

The implementation used here was copied from
drivers/net/ethernet/broadcom/tg3.c.

Ensure that the descriptor writes are visible before the ring buffer head
is updated. Since writel is a barrier, we can simply update the head after

Rob Herring 1a1d4d2f30 net: calxedaxgmac: fix possible skb free before tx complete
The TX completion code may have freed an skb before the entire sg list
was transmitted. The DMA unmap calls for the fragments could also get
skipped. Now set the skb pointer on every entry in the ring, not just
the head of the sg list. We then use the FS (first segment) bit in the
descriptors to determine skb head vs. fragment.

This also fixes similar bug in xgmac_free_tx_skbufs where clean-up of
a sg list that wraps at the end of the ring buffer would not get
unmapped.

It is possible for the xgmac_tx_complete to run concurrently with
xgmac_tx_err since there are no locks. Fix this by moving the tx
error handling to a workqueue so we can disable napi while we reset
the transmitter.

Claudiu Manoil 50ad076ba4 gianfar: Fix reported number of sent bytes to BQL
Fix the amount of sent bytes reported to BQL by reporting the
number of bytes on wire in the xmit routine, and recording that
value for each skb in order to be correctly confirmed on Tx
confirmation cleanup.

Reporting skb->len to BQL just before exiting xmit is not correct
due to possible insertions of TOE block and alignment bytes in the
skb->data, which are being stripped off by the controller before
transmission on wire.  This led to mismatch of (incorrectly)
reported bytes to BQL b/w xmit and Tx confirmation, resulting in
Tx timeout firing, for the h/w tx timestamping acceleration case.

There's no easy way to obtain the number of bytes on wire in the Tx
confirmation routine, so skb->cb is used to convey that information
from xmit to Tx confirmation, for now (as proposed by Eric). Revived
the currently unused GFAR_CB() construct for that purpose.

David S. Miller 6d508cce92 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next
Jeff Kirsher says:

====================
This series contains updates to ixgbe.

Jacob provides a fix for 82599 devices where it can potentially keep link
lights up when the adapter has gone down.

Mark provides a fix to resolve the possible use of uninitialized memory
by checking the return value on EEPROM reads.

Don provides 2 patches, one to fix a issue where we were traversing the
Tx ring with the value of IXGBE_NUM_RX_QUEUES which currently happens
to have the correct value but this is misleading.  A change later, could
easily make this no longer correct so when traversing the Tx ring, use
netdev->num_tx_queues.  His second patch does some minor clean ups of log
messages.

Emil provides the remaining ixgbe patches.  First he fixes the link test
where forcing the laser before the link check can lead to inconsistent
results because it does not guarantee that the link will be negotiated
correctly.  Then he initializes the message buffer array to 0 in order
to avoid using random numbers from the memory as a MAC address for the
VF.  Emil also fixes the read loop for the I2C data to account for the
offset for SFP+ modules.  Lastly, Emil provides several patches to add
support for QSFP modules where 1Gbps support is added as well as support
for older QSFP active direct attach cables which pre-date SFF-8436 v3.6.

v2: Fixed patch 4 description and added blank line based on feedback from
    Sergei Shtylyov

Ben Hutchings 8127d661e7 sfc: Add support for Solarflare SFC9100 family
This adds support for the EF10 network controller architecture and the
SFC9100 family, starting with SFC9120 'Farmingdale', and bumps the
driver version to 4.0.

New features in the SFC9100 family include:

- Flexible allocation of internal resources to PCIe physical and virtual
  functions under firmware control
- RX event merging to reduce DMA writes at high packet rates
- Integrated RX timestamping
- PIO buffers for lower TX latency
- Firmware-driven data path that supports additional offload features
  and filter types
- Delivery of packets between functions and to multiple recipients,
  allowing firmware to implement a vswitch
- Multiple RX flow hash (RSS) contexts with their own hash keys and
  indirection tables
- 40G MAC (single port only)

...not all of which are enabled in this initial driver or the initial
firmware release.

Much of the new code is by Jon Cooper.

Dan Carpenter 80b17be70b qlcnic: underflow in qlcnic_validate_max_tx_rings()
This function checks the upper bound but it doesn't check for negative
numbers:

	if (txq > QLCNIC_MAX_TX_RINGS) {

I've solved this by making "txq" a u32 type.  I chose that because
->tx_count in the ethtool_channels struct is a __u32.

This bug was added in aa4a1f7df7 ('qlcnic: Enable Tx queue changes using
ethtool for 82xx Series adapter.').
