Subject: [PATCH] wifi: ieee80211: don't require protected vendor action frames

From: Johannes Berg <[email protected]>

For vendor action frames, whether a protected one should be
used or not is clearly up to the individual vendor and frame,
so even though a protected dual is defined, it may not get
used. Thus, don't require protection for vendor action frames
when they're used in a connection.

Since we obviously don't process frames unknown to the kernel
in the kernel, it may makes sense to invert this list to have
all the ones the kernel processes and knows to be requiring
protection, but that'd be a different change.

Fixes: 91535613b609 ("wifi: mac80211: don't drop all unprotected public action frames")
