Eilon Greenstein f1ef27ef42 bnx2x: Disabling interrupts after iSCSI-boot
Before initializing the chip after iSCSI boot, the interrupts of the function
that was used to boot must be disabled. That means that the driver needs to set
the chip as if it is the iSCSI PCI function - this bug is exposed only with MSI

Eilon Greenstein 8badd27aa0 bnx2x: MSI support
Enabling MSI on top of MSI-X and INTA. Also changing the module parameter to
allow choosing INTA or MSI even when MSI-X is available. The default status
block should not be reversed for endianity. Since MSI can issue
re-configuration, the interrupt disable function now requires mmiowb

Eilon Greenstein 8d9c5f34a2 bnx2x: New FW
This is the FW blob and the relevant definitions without any logic. It
also contains the minimal mandatory code changes to work with this FW
but it does not contain enabling of the new features that this FW
provides.

This FW is needed for:
- More efficient multi-queue
- per queue statistics
- Big-endian issue with MSI
- Improved pause response

Patrick Ohly 33af6bcc00 igb: use timecompare to implement hardware time stamping
Both TX and RX hardware time stamping are implemented.  Due to
hardware limitations it is not possible to verify reliably which
packet was time stamped when multiple were pending for sending; this
could be solved by only allowing one packet marked for hardware time
stamping into the queue (not implemented yet).

RX time stamping relies on the flag in the packet descriptor which
marks packets that were time stamped. In "all packet" mode this flag
is not set. TODO: also support that mode (even though it'll suffer
from race conditions).

dave graham 0a834a36ac e1000e: Remove mutex_trylock and associated WARN on failure.
Single-thread access must be ensured for ICH8 NVM and PHY operations.
This synchronization is provided by the nvm_mutex. To assist in
understanding the contexts from which this code could be reached,
a WARN was output if the mutex was not going to be immediately
acquirable (if !mutex_trylock()). The code has now been optimized,
and we have verified that the few remaining mutex contentions are
reasonable and non-blocking, and it is time to remove the
mutex_trylock() and WARN messages.

Michael Chan 86f95f9eac bnx2: Update 5706/5708 firmware.
New firmware fixes a data corruption issue when receiving and
placing jumbo frames into host buffers.  In some cases, the
buffer descriptor is not updated correctly and this will lead
to the driver linking the wrong number of pages into the SKB.

The large receive buffer queue is not properly tracking the current

Reinette Chatre 89c581b3fb iwlwifi: fix suspend/resume and its usage of pci saved state
Here we do two things:

First, revert "iwlwifi: save PCI state before suspend, restore after
resume".  That misguided patch led to being unable to use iwlwifi
devices after resume.

Next, indicate to PCI driver that the saved PCI state is valid during suspend.

We restore PCI state and enable the device when network interface is created,
similarly PCI state is saved and the device is disabled when network interface
is removed. Thus, when .suspend is called the PCI state is saved and device
is disabled. This is the case even if an interface is never created as PCI
state is saved and device disabled during .probe.

PCI driver assumes PCI state is saved in .suspend. Saving the state at this
time will save state of disabled device and thus cause problems during
resume (resuming a disabled device). We thus indicate directly to PCI
driver that current PCI saved state is valid.

Meelis Roos 7b7a799d66 sunhme: Fix Quattro HME irq registration on proble failures
Currently, the sunhme driver installs SBus Quattro interrupt handler 
when at least one HME card was initialized correctly and at least one 
Quattro card is present. This breaks when a Quattro card fails 
initialization for whatever reason - IRQ is registered and OOPS happens 
when it fires.

The solution, as suggested by David Miller, was to keep track which 
cards of the Quattro bundles have been initialized, and request/free the 
Quattro IRQ only when all four devices have been successfully 
initialized.

The patch only touches SBus initialization - PCI init already resets the 
card pointer to NULL on init failure.

The patch has been tested on Sun E3500 with SBus and PCI single HME 
cards and one PCI Quattro HME card in a situation where any PCI card 
failed init when the SBus routines tried to init them by mistake.

Additionally it replaces Quattro request_irq panic with error return - 
if this card fails to work, at least let the others work.

Tested on E450 with PCI HME and PCI Quad HME.

not necessary, as the link can be monitored from the watchdog timer, and
the false link indications cease.

Gating can be disabled by directly setting the appropriate bit in the

Mike Rapoport 0c2bec9694 libertas: if_spi: add ability to call board specific setup/teardown methods
In certain cases it is required to perform board specific actions
before activating libertas G-SPI interface. These actions may include
power up of the chip, GPIOs setup, proper pin-strapping and SPI
controller config.
This patch adds ability to call board specific setup/teardown methods

Johannes Berg 7fee5372d8 mac80211: remove HW_SIGNAL_DB
Giving the signal in dB isn't much more useful to userspace
than giving the signal in unspecified units. This removes
some radiotap information for zd1211 (the only driver using
this flag), but it helps a lot for getting cfg80211-based
scanning which won't support dB, and zd1211 being dB is a
little fishy anyway.

Samuel Ortiz 8ccde88a87 iwl3945: Getting rid of the *39_rxon iwl_priv fields
The iwl_rxon_cmd is really just a iwl3945_rxon_cmd structure extension.
So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific
ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host
commands, since the command length as to be set according to the HW. As
another precaution the reserved4 and reserved5 fields are cleared before being
sent to the 3945.

With the *39_rxon removal, a lot of duplicated code can be removed from the
3945 code base.

Alex Williamson cfbf84fcbc tun: Fix unicast filter overflow
Tap devices can make use of a small MAC filter set via the
TUNSETTXFILTER ioctl.  The filter has a set of exact matches
plus a hash for imperfect filtering of additional multicast
addresses.  The current code is unbalanced, adding unicast
addresses to the multicast hash, but only checking the hash
against multicast addresses.  This results in the filter
dropping unicast addresses that overflow the exact filter.
The fix is simply to disable the filter by leaving count set
to zero if we find non-multicast addresses after the exact
match table is filled.

Ondrej Zary 152abd139c 3c509: Fix resume from hibernation for PnP mode.
From: Ondrej Zary <linux@rainbow-software.org>

last year, I posted a patch which fixed hibernation on 3c509
cards. That was back in 2.6.24. It worked fine in 2.6.25. But then I
stopped using hibernation (as it did not work with my new IT8212 RAID
controller).

Now I fixed it and noticed that 3c509 does not wake up properly
anymore (in 2.6.28) - neither in PnP nor in ISA modes. ifconfig
down/up makes the card work again in PnP mode. However, in ISA mode,
ifconfig up ends with "No such device" error.

Comparing the 3c509 driver between 2.6.25 and 2.6.28, there's only
some statistics-related change. So the cause of the problem must be
somewhere else.

This patch makes the resume work in PnP mode, but it's still not
enough for ISA mode.

Ilkka Virta 71822faa3b sungem: Soft lockup in sungem on Netra AC200 when switching interface up
From: Ilkka Virta <itvirta@iki.fi>

In the lockup situation the driver seems to go off in an eternal storm
of interrupts right after calling request_irq(). It doesn't actually
do anything interesting in the interrupt handler. Since connecting the link
afterwards works, something later in initialization must fix this.

Looking at gem_do_start() and gem_open(), it seems that the only thing
done while opening the device after the request_irq(), is a call to
napi_enable().

I don't know what the ordering requirements are for the
initialization, but I boldly tried to move the napi_enable() call
inside gem_do_start() before the link state is checked and interrupts
subsequently enabled, and it seems to work for me. Doesn't even break
anything too obvious...

Some Realtek chips (RTL8169sb/8110sb in my case) are unable to retrieve
ethtool statistics when the interface is down. The process stays in
endless loop in rtl8169_get_ethtool_stats. This is because these chips
need to have receiver enabled (CmdRxEnb bit in ChipCmd register) that is
cleared when the interface is going down. It's better to update statistics
only when the interface is up and otherwise return copy of statistics
grabbed when the interface was up (in rtl8169_close).

It is interesting that PCI-E NICs (like 8168b/8111b...) are not affected.

Peter P Waskiewicz Jr 34b0368c68 ixgbe: Display EEPROM version in ethtool -i queries
Currently ixgbe does not display the EEPROM version in ethtool -i, where
other drivers do.  The EEPROM version is located at offset 0x29.  This
patch adds support to display it.

Peter P Waskiewicz Jr 3201d3130e ixgbe: Update link setup code to better support autonegotiation of speed
The current code has some flaws in it when performing autonegotiation,
especially on KX/KX4 links.  This patch updates the code to better handle
the autonegotiation states on link setup.  The patch also removes a redundant
link configuration call on driver load, and moves link configuration to
the ->open() path.

Peter P Waskiewicz Jr bc97114d3f ixgbe: Refactor set_num_queues() and cache_ring_register()
The current code to determine the number of queues the device will want
on driver initialization is ugly and difficult to maintain.  It also
doesn't allow for easy expansion for future features or future hardware.
This patch refactors these routines, and make them easier to deal with.

Herbert Xu 33dccbb050 tun: Limit amount of queued packets per device
Unlike a normal socket path, the tuntap device send path does
not have any accounting.  This means that the user-space sender
may be able to pin down arbitrary amounts of kernel memory by
continuing to send data to an end-point that is congested.

Even when this isn't an issue because of limited queueing at
most end points, this can also be a problem because its only
response to congestion is packet loss.  That is, when those
local queues at the end-point fills up, the tuntap device will
start wasting system time because it will continue to send
data there which simply gets dropped straight away.

Of course one could argue that everybody should do congestion
control end-to-end, unfortunately there are people in this world
still hooked on UDP, and they don't appear to be going away
anywhere fast.  In fact, we've always helped them by performing
accounting in our UDP code, the sole purpose of which is to
provide congestion feedback other than through packet loss.

This patch attempts to apply the same bandaid to the tuntap device.
It creates a pseudo-socket object which is used to account our
packets just as a normal socket does for UDP.  Of course things
are a little complex because we're actually reinjecting traffic
back into the stack rather than out of the stack.

The stack complexities however should have been resolved by preceding
patches.  So this one can simply start using skb_set_owner_w.

For now the accounting is essentially disabled by default for
backwards compatibility.  In particular, we set the cap to INT_MAX.
This is so that existing applications don't get confused by the
sudden arrival EAGAIN errors.

In future we may wish (or be forced to) do this by default.
