Subject: Move RX-from-unknown-STA processing away from driver_*.c
X-Git-Tag: hostap_0_7_0~671
X-Git-Url: http://www.project-moonshot.org/gitweb/?a=commitdiff_plain;h=214021f585398d1908f6c221f56b3f0e3590acf4;p=libeap.git

Move RX-from-unknown-STA processing away from driver_*.c

This cleans up the driver wrapper interface by getting rid of sta_info.h
dependency in all drivers that use MLME implementation in hostapd
(driver_hostap.c and driver_nl80211.c).
