Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next into wireless
John W. Linville says:
====================
This is a big pull request for new features intended for the 3.10
stream...
Regarding mac80211, Johannes says:
"First, I merged mac80211/master to avoid some conflicts. This brings in
a bunch of fixes you're already familiar with. For real -next material,
I have a whole bunch of minstrel work, minstrel_ht from Felix and legacy
minstrel from Thomas (Huehn). The other Thomas (Pedersen) did a number
of changes in mesh to allow userspace peering management even when the
mesh isn't secured. Stanislaw changes suspend/resume to always
disconnect the networks. This is typically already done by
network-manager so won't make a huge difference for most users, but
fixes a number problems, particularly with USB drivers that can easily
disconnect while suspended. Ilan has a small change to allow mac80211
drivers to differentiate remain-on-channel reasons, and Jouni extends
nl80211 to allow fast roaming with full-MAC devices. I have a fairly
large number of patches as well, many of them fairly simple cleanups,
but also allowing split wiphy dumps and adding back the full wiphy
information in nl80211, station entry change checking and more VHT work
including VHT capability overrides (mostly for testing purposes)."
And for iwlwifi, Johannes says:
"Here, I also merged iwlwifi-fixes to avoid conflicts, and otherwise have
various cleanups and improvements on the MVM driver, along with a few
throughout the driver. Other than Bluetooth Coexistence from Emmanuel
there's no over-arching theme, so listing them would pretty much
reproduce the shortlog."
Regarding NFC, Samuel says:
"The 2 features we have with this one are:
- An LLCP Service Name Lookup (SNL) netlink interface for querying LLCP
service availability from user space.
Along the way, Thierry also improved the existing SNL interface for
aggregating SNL responses.
- An initial LLCP socket options implementation, for setting the Receive
Window (RW) and the Maximum Information Unit Extension (MIUX) per socket.
This is need for the LLCP validation tests.
We also have a microread MEI build failure here: I am not sending this one to
3.9 because the MEI bus code is not there yet, so it won't break for anyone
else than me."
And for ath6kl, Kalle says:
"I added tracing support to ath6kl, along with a new Kconfig option. Now
there's also a workaround to reset USB devices when the firmware upload
fails, this happened when host was warm rebooted. There are also quite a
few small fixes or cleanup."
On top of all that, there is the usual bundle of driver updates
with new features, new hardware support and the like mixed-in.
The ath9k, b43, brcmfmac, mwifiex, rt2800, and wil6210 drivers
are all well-represented, and a few other drivers are hit as well.
I also pulled-in the wireless fixes tree in order to resolve some
pending merge conflicts.
Please let me know if there are problems!
