Subject: [PATCH] mac80211: allow mode change if IBSS is not allowed
Date: Mon, 22 Dec 2008 16:39:36 -0500 [thread overview]
Message-ID: <20081222213935.26129.4212.stgit@dv.roinet.com> (raw)
Changing mode on an interface is not allowed if IBSS is disabled for the
current channel. That restriction should only apply when switching to
the ad-hoc mode, as it was prior to db17d8c4.
