Can we ignore frames with invalid BSSID in IBSS mode?

[Ben Greear]

It seems that ath10k ar988X hardware has a bug where the BSSID
for IBSS AMSDU frames is all zeros.  The 'main' 636 ath10k firmware
does not seem to use AMSDUs for IBSS, and when I enable it in my CT
firmware, then I see the breakage.  So, I suspect it is not
just a simple software/firmware bug.

If I simply ignore the bssid_match check in ieee80211_accept_frame,
then it seems everything runs fine.

So, I'm curious if anyone knows what sorts of bad things could happen
if the bssid_match check is ignored?  Maybe bcast/mcast frames could
be accepted when they shouldn't be in certain cases?

Thanks,
Ben
