Akeem G. Abodunrin 0ba96d3d91 igb: SERDES loopback sigdetect bit on i210 devices
This patch implements SERDES loopback configuration for i210 devices by
unsetting sigdetect bit, so as to fix Ethtool loopback test failure. Old
sigdetect code is also simplified to take care of all devices newer than 82580

Don Skidmore 345be204dc ixgbe: add SFP+ LX module support
This patch adds LX support to 82599 devices. This is an alternate patch to
the one suggested by Stefan Behte <s.behte@babiel.com>

In addition this patch includes some cleanups such as:
- removed parenthesis around "x == y ||" lines inside an if statement for
consistency.
- grouped the sx/lx sfp types along with srlr in ixgbe_get_settings() since
they all have the same supported, advertised and port values.

Jacob Keller 6b92b0ba75 ixgbe: rename wol_supported to more fitting wol_enabled
The variable wol_supported really is just checking whether it is enabled, rather
than whether it is supported. If it is enabled it will be supported, but this
does not necessarily hold true the other way around. This patch renames the
variable to avoid confusion.

Yuval Mintz 70632d0afe bnx2x: Allow recovery from second slot reset
As part of PCIe Advanced Error Reporting flow, if a fatal PCI error occurs,
the AER driver will cause bnx2x's PCI-core to reset. The driver's PCI error
handlers will in turn restore the PCI configuration space values by calling
`pci_restore_state'.

However, as bnx2x does not save the PCI configuration after restoration,
An additional fatal PCI error will leave the function in an unstable state
until reboot, as the registers in the PCI configuration space will contain
reset values.

Yuval Mintz 2f7a312230 bnx2x: Fix memory leak
There exists an `allocation race' between the CNIC and bnx2x drivers,
in which both drivers allocate the same t2 memory while disregarding a possible
previous allocation.

Additionally, due to the current order of memory releases, some of the
ILT memory in the driver is not released correctly when unloading the driver.

Yuval Mintz 2c2d06d512 bnx2x: prevent GRO false checksum claims
This patch introduces a more robust error handling flow in case of incorrect
behaviour by the FW when passing on GRO aggregations.

Although this should never happen (i.e., this is merely a theoretical fix),
if the bnx2x driver was to receive a GRO from FW with protocol other than
IPv4/IPv6, the driver would falsely claim to have performed partial
checksum and set various incorrect fields in the skb header.

Current behaviour of the bnx2x driver (i.e., print an error) is insufficient.
This patch remedies this by simply preventing the false claims.

The patch allows to enable/disable HW timestamping for incoming and/or

To enable/disable HW timestamping appropriate ioctl should be used.
Currently HWTSTAMP_FILTER_ALL/NONE and HWTSAMP_TX_ON/OFF only are
supported.
When enabling TS on receive flow - VLAN stripping will be disabled.
Also were made all relevant changes in RX/TX flows to consider TS request
and plant HW timestamps into relevant structures.

David S. Miller 8bfadc32b7 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:

====================
Here is one last(?) big wireless bits pull request before the merge window...

Regarding the mac80211 bits, Johannes says:

"Here's another big pull request for the -next stream. This one has a ton
of driver updates, which hopefully addresses all drivers, but maybe you
have more new drivers than I have in my tree? Not entirely sure, let me
know if this is the case and then I can merge wireless-next.

I'm including a large number of small changes, see the shortlog. The two
bigger things are making VHT compatible with not using channel contexts
(from Karl) and the stop-while-suspended fixes I developed together with
Stanislaw."

...and...

"This time I have a relatively large number of fixes and small
improvements, the most important one being Bob's RCU fix. The two big
things are Felix's work on rate scaling tables (with a big thanks to
Karl too) and my own work on CSA handling to finally properly handle HT
(and some VHT.)"

As for the iwlwifi bits, Johannes says:

"The biggest work here is Bluetooth coexistence and power saving. Other
than that, I have a few small fixes that weren't really needed for 3.9
and a new PCI ID."

About the NFC bits, Samuel says:

"With this one we have:

- A major pn533 update. The pn533 framing support has been changed in order to
  easily support all pn533 derivatives. For example we now support the ACR122
  USB dongle.

- An NFC MEI physical layer code factorization through the mei_phy NFC API.
  Both the microread and the pn544 drivers now use it.

- LLCP aggregation support. This allows NFC p2p devices to send aggregated
  frames containing all sort of LLCP frames except SYMM and aggregation
  frames.

- More LLCP socket options for getting the remote device link parameters.

- Fixes for the LLCP socket option code added with the first pull request for
  3.10.

- Some support for LLCP corner cases like 0 length SDUs and general DISC
  (tagged with a 0,0 dsap ssap couple) handling.

- RFKILL support for NFC."

For the b43 bits, Rafał says:

"Let me remind the changes for b43:
> Changes include:
> 1) Minor improvements for HT-PHY code (BCM4331)
> 2) Code cleaning for HT-PHY and N-PHY"

Concerning the bluetooth bits, Gustavo says:

"A set of changes intended for 3.10. The biggest changes here are from David
Herrmann, he rewrote most of the HIDP layer making it more reliable. Marcel
added a driver setup stage for device that need special handling on their
early initialization. Other than that we have the usual clean ups, bugfixes
and small improvements."

Along with all that, there is the usual collection of random/various
updates to ath9k, mwifiex, brcmfmac, brcmsmac, rt2x00, and wil6210.

I also included a pull of the wireless tree to resolve a merge conflict.

Please let me know if there are problems!

The RX fifo can be accessed from the common tasklet or it can
be reaped/cleaned when RX is stopped, which is done when doing
a reset or channel change - this happens in process context.

Since it is ensured that there are no pending tasklets when
stopping RX and cleaning the FIFO, there is no need to use
SKB queue functions which take internal locks.

GCC 4.8 is spitting out uninitialized-variable warnings against
"drivers/net/wireless/rtlwifi/rtl8192c/dm_common.c".  This patch adds
initialization to the variable and properly sets its value.

Mathias Kretschmer f77f823440 ath9k: apply coverage class on slottime too
According to 802.11-2007 17.3.8.6 (slot time), the slot time should
be increased by 3 us * coverage class. The code only increased the
ack timeout, which is fixed by this patch.

We have noticed in our long shot scenario that we see less collisions
with this patch.
