Subject: [PATCH AUTOSEL 4.14 07/36] mac80211_hwsim: correct use of
 IEEE80211_VHT_CAP_RXSTBC_X

From: Danek Duvall <duvall@...fychair.org>

[ Upstream commit d7c863a2f65e48f442379f4ee1846d52e0c5d24d ]

The mac80211_hwsim driver intends to say that it supports up to four
STBC receive streams, but instead it ends up saying something undefined.
The IEEE80211_VHT_CAP_RXSTBC_X macros aren't independent bits that can
be ORed together, but values.  In this case, _4 is the appropriate one
to use.
