Date: Sat, 8 May 2010 23:40:23 +0200 Message-Id: <1273354826-4335-7-git-send-email-gwingerde@gmail.com> In-Reply-To: <1273354826-4335-1-git-send-email-gwingerde@gmail.com> References: <1273354826-4335-1-git-send-email-gwingerde@gmail.com> Sender: linux-wireless-owner@vger.kernel.org List-ID: With a little bit of restructuring it isn't necessary to have special cases in rt2x00queue_write_tx_descriptor for writing the descriptor for beacons. Simply split off the kicking of the TX queue to a separate function with is only called for non-beacons.
