From 077f49392819608084c6d8d20e3dcca230afe07d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 20 Jan 2012 13:55:18 +0100 Subject: [PATCH] mac80211: simplify AP_VLAN handling Setting keys and updating TKIP keys must use the BSS sdata (not AP_VLAN), so we translate. Move the translation into driver-ops wrappers instead of having it inline in the code to simplify the normal code flow. The same can be done for sta_add/remove which already does the translation in the wrapper. Signed-off-by: Johannes Berg Signed-off-by: John W.
