Subject: [RFC 1/3] mac80211: move cmntr flag out of rx flags
Date: Mon, 16 Nov 2009 15:21:35 +0100	[thread overview]
Message-ID: <20091116142412.978249174@sipsolutions.net> (raw)
In-Reply-To: 20091116142134.288122270@sipsolutions.net

The RX flags should soon be used only for flags
that cannot change within an a-MPDU, so move the
cooked monitor flag into the RX status flags.
