bc73902a03 ath9k: Update mac_postamble for AR9003 family
Enable the ALWAYS_KEYSEARCH bit in the initvals. Currently
this is done in the driver, but adding this to the initvals
makes it easier to be in sync with the INI files given
by the systems engineering team.

b3b06a3254 iwlwifi: mvm: rs: overhaul search cycle state machine
Rewrite the search cycle state machine to use a more data
oriented approach where the different Tx columns (configs)
limitations and next columns to search are reprsented in
tables which are easy to change. This overhaul also includes
several major fixes:

1. Prevent going back to a specific Tx column in a search
cycle if it was already explored.

2. Avoid switching to a Tx column that doesn't have any chance
if it performs perfectly to beat the current throughput we're
getting.

These issues were degrading throughput as they were causing
switching to "bad" Tx columns.

da87d7d5e7 iwlwifi: mvm: rs: fix mapping from HT/VHT rates to legacy
The table rs_ht_to_legacy is used to get the next legacy rate
following the last HT or VHT rate in the LQ rates table.
The mapping wasn't correct as well as didn't include entries
for MCS8/9 which led to out of bounds access. This didn't
trigger a crash but led to legacy rate entries using 1Mbps
rate.
In 5Ghz this probably caused the Tx to fail completely given
that Tx attempt would have reached the legacy entries and 1Mbps
isn't valid.

9d015a0334 iwlwifi: mvm: rs: update expected TPT tables if aggregation changed
Expected TPT table was updated only when switching to a new
modulation. This is wrong as toggling aggregation changes
the expected TPT signficantly.
This leads to scenarios where turning aggregation on after
being in MIMO sends us back to SISO despite a perfect success
ratio.
This occurred because the TPT of the SISO mode was being
estimated based on aggregation while the MIMO one wasn't.

Also remove an error print which isn't an error anymore
since we might be updating the expected TPT table due
to aggregation changes.

6b294b8efe sfc: Poll for MCDI completion once before timeout occurs
There is an as-yet unexplained bug that sometimes prevents (or delays)
the driver seeing the completion event for a completed MCDI request on
the SFC9120.  The requested configuration change will have happened
but the driver assumes it to have failed, and this can result in
further failures.  We can mitigate this by polling for completion
after unsuccessfully waiting for an event.

d4fb84eefe virtio: delete napi structures from netdev before releasing memory
free_netdev calls netif_napi_del too, but it's too late, because napi
structures are placed on vi->rq. netif_napi_add() is called from
virtnet_alloc_queues.

There's an issue when showing the value of packets_per_slave due to

reciprocal_value() before showing. This patch makes it use unsigned
integer when showing it.

During suspend-resume and lancer error recovery we will cleanup and
re-initialize the resources through be_clear() and be_setup() respectively.
During re-initialisation in be_setup(), if be_get_config() fails, we'll again
call be_clear() which will cause a NULL pointer dereference as adapter->pmac_id is
already freed.

b0ac956406 arc_emac: remove custom "max-speed" parsing code
The ARC emac driver was the only in-tree to parse a PHY device
'max-speed' property but yet failed to do it correctly because
'max-speed' is supposed to set a PHY device supported features, not the
advertising features as it was done.

Now that of_mdiobus_register() takes care of doing that, remove the
custom 'max-speed' parsing code.

Jeff Kirsher says:

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

This series contains updates to i40e only.

Christopher Pau provides a patch to set pf_id based on device and
function numbers since NICs with ARI enabled can have function
numbers larger than 8.

Anjali provides 3 i40e patches to update hardware defines to keep
in sync with hardware updates.

Shannon provides the majority of i40e patches, with 7.  First patch
clears the admin queue head and tail registers during admin queue
shutdown. Then simplifies the admin queue head-tail-len setups to
use more virtual registers.  Provides several patches to cleanup
and fix driver load and reset procedures to make more robust.  Lastly,
provides an ethtool test for interrupts using the software interrupt.

Mitch provides some i40e patches which fixes up VF code in the PF
driver, specifically the number of vectors per VF are reported by the
hardware does not include vector 0, so we need to account for this
when checking.  In addition, cleans up debugging messages.

Kamil provides an i40e patch to fix the diagnostics test by restricting
the diagnostic test length.

dd0df47dc3 net: davinci_emac: Fix platform data handling and make usable for am3517
When booted with device tree, we may still have platform data passed
as auxdata. For am3517 this is needed for passing the interrupt_enable
and interrupt_disable callbacks that access the omap system control module
registers. These callback functions will eventually go away when we have
a separate system control module driver.

Some of the things that are currently passed as platform data we don't need
to set up as device tree properties as they are always the same on am3517.
So let's use a new compatible flag for those so we can get those from
the device tree match data.

Also note that we need to fix setting of phy_dev to NULL instead of an empty
string as the code later on uses that to find the first phy on the mdio bus.
This seems to have been caused by 5d69e0076a (net: davinci_emac: switch to
new mdio).

with a fragment header even if they are not a fragment - i.e. offset is zero,
and M bit is not set).

This patch also incorporates a fix to callers of maybe_pull_tail() where
skb->network_header was being erroneously added to the length argument.

So modify macvtap creation to automatically forward a creation of a

underlying network device, just like is currently done with
macvlan-on-macvlan devices.

67fa36609f xen-netback: clear vif->task on disconnect
xenvif_start_xmit() relies on checking vif->task for NULL to determine
whether the vif is ready to accept packets. The task thread is stopped in
xenvif_disconnect() but task is not set to NULL. Thus, on a re-connect the
check will give a false positive.

Also since commit ea732dff5c (Handle backend
state transitions in a more robust way) it should not be possible for
xenvif_connect() to be called if the vif is already connected so change the
check of vif->tx_irq to a BUG_ON() and also add a BUG_ON(vif->task).

2488a54e48 net: fec_main: dma_map() only the length of the skb
On tx submit the driver always dma_map_single() FEC_ENET_TX_FRSIZE (=2048)
bytes. This works because we don't overwrite any memory after the data buffer,
we remove it from cache if it was there. So we hurt performace in case the
mapping of a smaller area makes a difference.
There is also a bug: If the data area starts shortly before the end of
RAM say 0xc7fffa10 and the RAM ends at 0xc8000000 then we have enough
space to fit the data area (according to skb->len) but we would map beyond
end of ram if we are using 2048. In v2.6.31 (against which kernel this patch
made) there is the following check in dma_cache_maint():

|BUG_ON(!virt_addr_valid(start) || !virt_addr_valid(start + size - 1));

Since the area starting at 0xc8000000 is no longer virt_addr_valid() we
BUG() during dma_map_single(). The BUG() statement was removed in v3.5-rc1 as
per 2dc6a016 ("ARM: dma-mapping: use asm-generic/dma-mapping-common.h").

This patch was tested on v2.6.31 and then forward-ported and compile
tested only against the net tree. I think it is still worth fixing
mainline even after the BUG() statement is gone.

Modify tg3_chip_reset() and tg3_close() to check if the PCI network
adapter device is accessible at all in order to skip poking it or
trying to handle a carrier loss in vain when that's not the case.
Introduce a special PCI helper function pci_device_is_present()
for this purpose.

Of course, this uncovers the lack of the appropriate RTNL locking
in tg3_suspend() and tg3_resume(), so add that locking in there
too.

These changes prevent tg3 from burning a CPU at 100% load level for
solid several seconds after the Thunderbolt link is disconnected from
