From c951ad3550ab40071bb0f222ba6125845769c08a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 16 Nov 2009 12:00:38 +0100 Subject: mac80211: convert aggregation to operate on vifs/stas The entire aggregation code currently operates on the hw pointer and station addresses, but that needs to change to make stations purely per-vif; As one step preparing for that make the aggregation code callable with the station, or by the combination of virtual interface and station address.
