Subject: Check rx_mgmt::frame more consistently against NULL
X-Git-Tag: hostap_2_2~214
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c0333c8dd59b9e254d3fc725c984b1c0cd3d496a;p=thirdparty%2Fhostap.git

Check rx_mgmt::frame more consistently against NULL

If a driver wrapper misbehaves and does not indicate a frame body in the
event, core hostapd code should handle this consistently since that case
was already checked for in one location.
