[PATCH 0/2][trusty] Fixes for disconnections due to beacon loss with Intel 7260 wireless

[Seth Forshee]

BugLink: http://bugs.launchpad.net/bugs/1349572

I think the root cause here is really a problem in the firmware, but
these patches offer substantial improvement even if they don't
completely eliminate the disconnections. I'll also be submitting these
patches for upstream stable, once I determine which other stable kernels
could benefit.


== SRU Justification ==

Impact: Many users with Intel 7260 wireless are seeing relatively
frequent disconnections as a result of the firmware reporting loss of
beacons from the access point.

Fix: Two upstream cherry picks, one which waits for several lost beacon
reports before reporting beacon loss to mac80211, and another which
fixes a bug with mac80211's handling of beacon loss reports from some
drivers (in particular iwlwifi).

Test Case: Tested on LP#1349572.

Regression Potential: These patches were merged upstream in 3.14 and
3.15 without any reported regressions.
