This patch sets the protocol selector bits (4:0) of the PHY's MII_ADVERTISE
register (ANAR) when writing ADVERTISE_ALL. The protocol selector bits are
indicating IEEE 803.3u support and are fixed / read-only on some PHYs. Not
setting them correctly on others (like TI DP83630) makes the PHY fall back
to 10M HDX mode which should be avoided.
Tested for TI DP83630 PHY on Microblaze platform.

It was recently found out that GSO on 57710/57711 was broken, due to packets
being sent without a valid IP checksum.
Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this
issue, but failed to set the correct IP checksum when receiving GSO packets
via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed
to calculate IP checksum were erroneously set in the incorrect
buffer descriptor.
This patch re-enables GSO in said scenario for 57710/57711 chips.

====================
here are there fixes for the v3.10 release cycle:
The first patch by Jonas Peterson and Olivier Sobrie fixes the reception of CAN
frames on Kvaser's "USBcan Pro" and "USBcan R" type hardware.
The last two patches by Olivier Sobrie (for esd_usb2) and me (for peak_usb)
change the memory handling for the USB messages from stack to kmalloc(), as
memory used for DMA should not be allocated on stack.

MAC addresses assigned by the PF to VFs were not kept in the PF driver
admin table. As a result, displaying the VF MACs from the PF interface
to user space showed zero address where in fact the VF got non-zero
address from the PF, fix that.

In the PF initialization, SRIOV is enabled before the PF is fully initialized.
This allows the kernel to probe the newly-exposed VFs before the PF is ready
to handle them (nested probes).
Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.

====================
Please pull this batch of fixes intended for the 3.10 stream...
Regarding the NFC bits, Samuel says:
"This is the first batch of NFC fixes for 3.10, and it contains:
- 3 fixes for the NFC MEI support:
* We now depend on the correct Kconfig symbol.
* We register an MEI event callback whenever we enable an NFC device,
otherwise we fail to read anything after an enable/disable cycle.
* We only disable an MEI device from its disable mey_phy_ops,
preventing useless consecutive disable calls.
- An NFC Makefile cleanup, as I forgot to remove a commented out line when
moving the LLCP code to the NFC top level directory."
As for the mac80211 bits, Johannes says:
"This time I have a fix from Stanislaw for a stupid mistake I made in the
auth/assoc timeout changes, a fix from Felix for 64-bit traffic counters
and one from Helmut for address mask handling in mac80211. I also have a
few fixes myself for four different crashes reported by a few people."
And Johannes says this about the iwlwifi bit:
"This fixes a brown paper-bag bug that we really should've caught in
review. More details in the changelog for the fix."
On top of that...
Arend van Spriel and Hante Meuleman cooperate to send a series of AP
and P2P mode fixes for brcmfmac.
Gabor Juhos corrects a register offset for AR9550, avoiding a bus
error.
Dan Carpenter provides a fixup to some dmesg output in the atmel
driver.
And, finally...
Felix Fietkau not only gives us a trio of small AR934x fixes, but
also refactors the ath9k aggregation session start/stop handling
(using the generic mac80211 support) in order to avoid a deadlock.
Please let me know if there are problems!

During a PCI EEH/AER error recovery flow, if the device did not successfully
restart, the error_detected() hook may be called a second time with a
"perm_failure" state. This patch skips over driver cleanup for the second
invocation of the callback.

We currently allow changing the mq flag (IFF_MULTI_QUEUE) for a persistent
device. This will result a mismatch between the number the queues in netdev and
tuntap. This is because we only allocate a 1q netdevice when IFF_MULTI_QUEUE was
not specified, so when we set the IFF_MULTI_QUEUE and try to attach more queues
later, netif_set_real_num_tx_queues() may fail which result a single queue
netdevice with multiple sockets attached.
Solve this by disallowing changing the mq flag for persistent device.
Bug was introduced by commit edfb6a148c
(tuntap: reduce memory using of queues).
