Subject: [RFC 06/12] mac80211: notify bridge when leaving mesh
Date: Thu, 2 May 2013 19:33:56 -0700 [thread overview]
Message-ID: <1367548442-8229-7-git-send-email-thomas@cozybit.com> (raw)
In-Reply-To: <1367548442-8229-1-git-send-email-thomas@cozybit.com>
After turning carrier off, any parent bridge interface
needs to be notified. Otherwise we would see a panic when
attempting to transmit frames on a mesh interface which
hadn't yet been put down.
