Subject: [PATCH 42/47] iwlagn: use iwl_sta_id() for aggregation
Date: Mon, 10 May 2010 15:28:13 -0700	[thread overview]
Message-ID: <1273530498-11876-43-git-send-email-reinette.chatre@intel.com> (raw)
In-Reply-To: <1273530498-11876-1-git-send-email-reinette.chatre@intel.com>

From: Johannes Berg <johannes.berg@intel.com>

With the station ID being stored in the
station struct, which mac80211 gives us
for aggregation callbacks, we can also
remove the use of iwl_find_station() in
those code paths.
