From 76d5a9e83b6e72ebe651c08e6dc247a58469ddda Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 2 Nov 2009 16:08:34 -0800 Subject: [PATCH] ath9k: use correct hw for tx aggregation TX completion When ath9k virtual wiphys are used the sc->hw will not always represent the active hw, instead we need to get it from the skb->cb private driver area. This ensures the right hw is used to find a sta for the TX'd skb. Cc: Jouni.Malinen Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
