generic ieee80211_sta_commit()?

["Alina Friedrichsen" <x-alina@gmx.net>]

Hello,

after a "ip link set wlan0 down" and than "ip link set wlan0 up" the wi=
fi connection don't come up again. If you do a "iwconfig wlan0 channel =
4" beaconing in IBSS doesn't work anymore.

My thought to fix this is to add a generic ieee80211_sta_commit() funct=
ion which is called after the most config changes (e.g. SSID, BSSID, ch=
annel, interface up, ...), so that a clean rejoin is done by the functi=
on and the driver hangs not in an undefined state. And I think it's mor=
e elegant, because ieee80211_sta_set_bssid() then doesn't need to call =
ieee80211_sta_set_ssid() anymore to do the rejoin.

What do you think about it? If agree I will implement it after Johannes=
 IBSS changes are applied to avoid confusion.

Regards
Alina
