Yuval Mintz 0189efb8f4 qed*: Fix Kconfig dependencies with INFINIBAND_QEDR
The qedr driver would require a tristate Kconfig option [to allow
it to compile as a module], and toward that end we've added the
INFINIBAND_QEDR option. But as we've made the compilation of the
qed/qede infrastructure required for RoCE dependent on the option
we'd be facing linking difficulties in case that QED=y or QEDE=y,
and INFINIBAND_QEDR=m.

To resolve this, we seperate between the INFINIBAND_QEDR option
and the infrastructure support in qed/qede by introducing a new
QED_RDMA option which would be selected by INFINIBAND_QEDR but would
be a boolean instead of a tristate; Following that, the qed/qede is
fixed based on this new option so that all config combinations would
be supported.

Ram Amrani cee9fbd8e2 qede: Add qedr framework
Adds a skeletal implementation of the qede RoCE driver -
The qedr has some dependencies of the state of the underlying base
interface. This adds some logic required with mutual registrations

Moshe Shemesh 79aab093a0 net: Update API for VF vlan protocol 802.1ad support
Introduce new rtnl UAPI that exposes a list of vlans per VF, giving
the ability for user-space application to specify it for the VF, as an
option to support 802.1ad.
We adjusted IP Link tool to support this option.

For future use cases, the new UAPI supports multiple vlans. For now we
limit the list size to a single vlan in kernel.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older versions of IP Link tool.

Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
We kept 802.1Q as the drivers' default vlan protocol.
Suitable ip link tool command examples:
  Set vf vlan protocol 802.1ad:
    ip link set eth0 vf 1 vlan 100 proto 802.1ad
  Set vf to VST (802.1Q) mode:
    ip link set eth0 vf 1 vlan 100 proto 802.1Q
  Or by omitting the new parameter
    ip link set eth0 vf 1 vlan 100

Yuval Mintz d8c2c7e340 qed*: Add support for VFs over legacy PFs
Modern VFs can't run on old non-compatible as the fastpath HSI is
slightly changed - but as the HSI is actually very close [basically,
a single bit whose meaning flipped] this can be supported with small
modifications.

The major differences would be in:
  - Recognizing that VF is running on top of a legacy PF.
  - Returning some slowpath configurations that are no longer needed
    on top of modern PFs, but would be required when working over
    the legacy ones.

Yuval Mintz 05fafbfb3d qed: utilize FW 8.10.10.0
This new firmware for the qed* adpaters fixes several issues:
 - Better blocking of malicious VFs.
 - After FLR, Tx-switching [internal routing] of packets might
   be incorrect.
 - Deletion of unicast MAC filters would sometime have side-effect
   of corrupting the MAC filters configred for a device.
It also contains fixes for future qed* drivers that *hopefully* would be
sent for review in the near future.

In addition, it would allow driver some new functionality, including:
 - Allowing PF/VF driver compaitibility with old drivers [running
   pre-8.10.5.0 firmware].
 - Better debug facilities.

This would also bump the qed* driver versions to 8.10.9.20.

Yuval Mintz 039a392733 qede: Fix Tx timeout due to xmit_more
Driver uses netif_tx_queue_stopped() to make sure the xmit_more
indication will be honored, but that only checks for DRV_XOFF.

At the same time, it's possible that during transmission the DQL will
close the transmission queue with STACK_XOFF indication.
In re-configuration flows, when the threshold is relatively low, it's
possible that the device has no pending tranmissions, and during
tranmission the driver would miss doorbelling the HW.
Since there are no pending transmission, there will never be a Tx
completion [and thus the DQL would not remove the STACK_XOFF indication],
eventually causing the Tx queue to timeout.

While we're at it - also doorbell in case driver has to close the
transmission queue on its own [although this one is less important -
if the ring is full, we're bound to receive completion eventually,
which means the doorbell would only be postponed and not indefinetly
blocked].

Yuval Mintz c524e2f5b7 qede: Don't try removing unconfigured vlans
As part of ndo_vlan_rx_kill_vid() implementation,
qede is requesting firmware to remove the vlan filter.
This currently happens even if the vlan wasn't previously
added [In case device ran out of vlan credits].

For PFs this doesn't cause any issues as the firmware
would simply ignore the removal request. But for VFs their
parent PF is holding an accounting of the configured vlans,
and such a request would cause the PF to fail the VF's
removal request.

Simply fix this for both PFs & VFs and don't remove filters
that were not previously added.

When handling IP fragmented packets with csum in their

passes on the wire. As a result, on receive path HW would
give an indication that the packet has incorrect csum,
which would cause qede to discard the incoming packet.

change driver behavior to pass such incoming packets
to stack and let it make the decision whether it needs
to be dropped.

drivers/net/ethernet/qlogic/qed/qed_main.c:1170:35: error: 'link_caps' may be used uninitialized in this function [-Werror=maybe-uninitialized]

While this warning is only about the specific case of CONFIG_QED_SRIOV
being disabled but the function getting called for a VF (which should
never happen), another possibility is that qed_mcp_get_*() fails without
returning data.

This rearranges the code so we bail out in either of the two cases
and print a warning instead of accessing the uninitialized data.

The qed_link_output structure remains untouched in this case, but
all callers first call memset() on it, so at least we are not leaking
stack data then.

As discussed, we also use a compile-time check to ensure we never
use any of the VF code if CONFIG_QED_SRIOV is disabled, and the
PCI device table is updated to no longer bind to virtual functions
in that configuration.

VF is currently ignoring the minimum provided by the API,
mistakenly using the maximum for minimum as well.

Linus Torvalds 087afe8aaf Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes and more updates from David Miller:

 1) Tunneling fixes from Tom Herbert and Alexander Duyck.

 2) AF_UNIX updates some struct sock bit fields with the socket lock,
    whereas setsockopt() sets overlapping ones with locking.  Seperate
    out the synchronized vs.  the AF_UNIX unsynchronized ones to avoid
    corruption.  From Andrey Ryabinin.

 3) Mount BPF filesystem with mount_nodev rather than mount_ns, from
    Eric Biederman.

 4) A couple kmemdup conversions, from Muhammad Falak R Wani.

 5) BPF verifier fixes from Alexei Starovoitov.

 6) Don't let tunneled UDP packets get stuck in socket queues, if
    something goes wrong during the encapsulation just drop the packet
    rather than signalling an error up the call stack.  From Hannes
    Frederic Sowa.

 7) SKB ref after free in batman-adv, from Florian Westphal.

 8) TCP iSCSI, ocfs2, rds, and tipc have to disable BH in it's TCP
    callbacks since the TCP stack runs pre-emptibly now.  From Eric
    Dumazet.

 9) Fix crash in fixed_phy_add, from Rabin Vincent.

10) Fix length checks in xen-netback, from Paul Durrant.

11) Fix mixup in KEY vs KEYID macsec attributes, from Sabrina Dubroca.

12) RDS connection spamming bug fixes from Sowmini Varadhan

Manish Chopra 09ec8e7fb6 qede: Fix DMA address APIs usage
Driver incorrectly uses dma_unmap_addr_set() to set
a variable which is in truth a dma_addr_t
[i.e not defined using DEFINE_DMA_UNMAP_ADDR()] and is
being used by the driver flows other than unmapping
physical addresses. This patch fixes driver fastpath
where CONFIG_NEED_DMA_MAP_STATE is not set.

Joonsoo Kim 0139aa7b7f mm: rename _count, field of the struct page, to _refcount
Many developers already know that field for reference count of the
struct page is _count and atomic type.  They would try to handle it
directly and this could break the purpose of page reference count
tracepoint.  To prevent direct _count modification, this patch rename it
to _refcount and add warning message on the code.  After that, developer
who need to handle reference count will find that field should not be
accessed directly.

Joonsoo Kim 6d061f9f61 mm/page_ref: use page_ref helper instead of direct modification of _count
page_reference manipulation functions are introduced to track down

Yuval Mintz 831bfb0e88 qed*: Tx-switching configuration
Device should be configured by default to VEB once VFs are active.
This changes the configuration of both PFs' and VFs' vports into enabling

and `ndo_set_vf_rate' which would allow the PF to limit the VF speed.

While a MAC is forced, PF would prevent the VF from configuring any other
