====================
pull-request: wireless-drivers-next 2016-07-22
I'm sick so I have to keep this short, but here's the last pull request
to net-next. This time there's a trivial conflict with mtd tree:
http://lkml.kernel.org/g/20160720123133.44dab209@canb.auug.org.au
We concluded with Brian (CCed) that it's best that we ask Linus to fix
this. The patches have been in linux-next for a couple of days. This
time I haven't done any merge tests so I don't know if there are any
other conflicts etc.
Please let me know if there are any problems.
wireless-drivers-next patches for 4.8
Major changes:
wl18xx
* add initial mesh support
bcma
* serial flash support on non-MIPS SoCs
ath10k
* enable support for QCA9888
* disable wake_tx_queue() mac80211 op for older devices to workaround
throughput regression
ath9k
* implement temperature compensation support for AR9003+
====================
