Subject: Don't unset dev->stop, it's dangerous to mess with netdev internals
X-Git-Url: http://git.ozo.com/?a=commitdiff_plain;h=ac79ec61827a3bf57238d7dad17c328684977228;p=madwifi%2F.git

Don't unset dev->stop, it's dangerous to mess with netdev internals

Instead, unset IFF_RUNNUNG on the interface - this suppresses most
functionality of ath_stop().
