Subject: [PATCH 5/5] ath9k: make the driver specific rate control module optional
Date: Mon, 20 Sep 2010 13:45:40 +0200 [thread overview]
Message-ID: <1284983140-30099-5-git-send-email-nbd@openwrt.org> (raw)
In-Reply-To: <1284983140-30099-4-git-send-email-nbd@openwrt.org>
ath9k can use minstrel_ht instead, so it makes sense to save some space here.
