[patch 01/43] ath5k: fix mesh point operation

[Greg KH]

2.6.28-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Andrey Yurovsky <andrey@xxxxxxxxxxx>

commit b706e65b40417e03c2451bb3f92488f3736843fa upstream.

This patch fixes mesh point operation (thanks to YanBo for pointing
out the problem): make mesh point interfaces start beaconing when
they come up and configure the RX filter in mesh mode so that mesh
beacons and action frames are received.  Add mesh point to the check
in ath5k_add_interface.  Tested with multiple AR5211 cards.
