From 43ec72b75a8851b48e561c29f49586cc747bdad8 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 10 Mar 2016 11:55:44 +0100 Subject: [PATCH] iwlwifi: mvm: pass station to mac80211 RX where known When we've already looked up the transmitter station, we can just pass it to mac80211 using the new ieee80211_rx_napi(). This saves the overhead of looking it up in mac80211 again.
