From 8bca5d815311f53ada13b62f5e590df40fef317e Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 13 Jul 2011 19:50:34 +0200 Subject: mac80211: allow driver access to TKIP RX P1K When the driver wants to pre-program the TKIP RX phase 1 key, it needs to be able to obtain it for the peer's TA. Add API to allow it to generate it. The generation uses a dummy on-stack context since it doesn't know the RX queue. Signed-off-by: Johannes Berg Signed-off-by: John W.
