Subject: mac80211: Clear PS related flag on disabling power save.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=db28569adc692d9fb8a2d2d8e7ebab7fd5481f10;p=openwrt%2Fstaging%2Fblogic.git

mac80211: Clear PS related flag on disabling power save.

Clear IEEE80211_STA_NULLFUNC_ACKED flag on disabling power
save. Without this fix, there is a chance of setting CONF_PS
before sending nullfunc frame.
