Subject: wl1271: Fix mac80211 RTS threshold requests during WL1271_STATE_OFF
X-Git-Tag: v2.6.35-rc1~473^2~167^2~313
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aecb0565e3e331d4dd23b4d35180519532015f22;p=profile%2Fivi%2Fkernel-x86-ivi.git

wl1271: Fix mac80211 RTS threshold requests during WL1271_STATE_OFF

mac80211 sends RTS threshold configuration request even if the wl1271 interface
state is WL1271_STATE_OFF. This leads to failures during pm tests.

This patch leaves the configuration function, if the interface is
going down.
