From 619753ff57a2e15b58546b856536928d1a3daef9 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 30 Apr 2010 11:30:46 -0700 Subject: [PATCH] iwlagn: use iwl_sta_id() for aggregation 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.
