From: Martin Willi <martin@strongswan.org>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 62397da50bb20a6b812c949ef465d7e69fe54bb6 upstream.
A wmediumd that does not send this attribute causes a NULL pointer
dereference, as the attribute is accessed even if it does not exist.
The attribute was required but never checked ever since userspace frame
forwarding has been introduced. The issue gets more problematic once we
allow wmediumd registration from user namespaces.
Fixes: 7882513bacb1 ("mac80211_hwsim driver support userspace frame tx/rx")
