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 <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
