wl1271: Prevent dropping of TX frames in joins
The wl1271 uses a session counter in CMD_JOIN and TX frame descriptors. This
counter is used to determine which frames to drop when the CMD_JOIN is
executed.
The driver executes CMD_JOIN multiple times upon association and sometimes
disassociation, and we don't want any frames to get lost.
Fix this by incrementing the session counter only when leaving idle (not every
CMD_JOIN as before.) Also, remove the TX flush flag from the CMD_JOIN options.

the buffer, then I changed snprintf to sprintf(). It's confusing to use
the return value of snprintf() as a limitter without verifying that it's
smaller than size. This is what initially caught my attention here.
If we use the return value of sprintf() instead future code auditors will
assume we've verified that it fits already.
Also I did find some places where it made sense to use the return value
after we've verified that it is smaller than the buffer size.
Finally the read_file_rcstat() function added an explicit NULL terminator
before calling snprintf(). That's unnecessary because snprintf() will
add the null terminator automatically.

iwlwifi: fix internal scan race
It is possible for internal scan to race against itself if the device is
not returning the scan results from first requests. What happens in this
case is the cleanup done during the abort of the first internal scan also
cleans up part of the new scan, causing it to access memory it shouldn't.
Here are details:
* First internal scan is triggered and scan command sent to device.
* After seven seconds there is no scan results so the watchdog timer
triggers a scan abort.
* The scan abort succeeds and a SCAN_COMPLETE_NOTIFICATION is received for
failed scan.
* During processing of SCAN_COMPLETE_NOTIFICATION we clear STATUS_SCANNING
and queue the "scan_completed" work.
** At this time, since the problem that caused the internal scan in first
place is still present, a new internal scan is triggered.
The behavior at this point is a bit different between 2.6.34 and 2.6.35
since 2.6.35 has a lot of this synchronized. The rest of the race
description will thus be generalized.
** As part of preparing for the scan "is_internal_short_scan" is set to
true.
* At this point the completion work for fist scan is run. As part of this
there is some locking missing around the "is_internal_short_scan"
variable and it is set to "false".
** Now the second scan runs and it considers itself a real (not internal0
scan and thus causes problems with wrong memory being accessed.
The fix is twofold.
* Since "is_internal_short_scan" should be protected by mutex, fix this in
scan completion work so that changes to it can be serialized.
* Do not queue a new internal scan if one is in progress.

OOO packets.
Because the input_pkt_queue has been effectively split into two queues,

gro: Fix bogus gso_size on the first fraglist entry
When GRO produces fraglist entries, and the resulting skb hits
an interface that is incapable of TSO but capable of FRAGLIST,
we end up producing a bogus packet with gso_size non-zero.
This was reported in the field with older versions of KVM that
did not set the TSO bits on tuntap.
This patch fixes that.

ixgbe:add support for a new 82599 10G Base-T device
This adds support for a new copper device for 82599, device id 0x151c.
This 82599 10GBase-T device uses the PHY's internal temperature sensor
to guard against over-temp conditions. In this scenario the PHY will be
put in a low power mode and link will no longer be able to transmit or
receive any data. When this occurs, the over-temp interrupt is latched
and driver logs this error message. A HW reset or power cycle is
required to clear this status.
