Subject: [PATCH] wl12xx: check the vif's operstate after join
Date: Mon, 6 Jun 2011 13:03:12 +0300 [thread overview]
Message-ID: <1307354592-32685-1-git-send-email-eliad@wizery.com> (raw)
When resuming while connected (without wowlan), the interface
is already IF_OPER_UP, so we won't get the notifier callback,
and hence never complete the association (from wl12xx perspective)
This situation, among other potential problems, prevents the
station from entering psm.

(this patch depends on the "mac80211: add ieee80211_get_operstate() function"
