What did you upgrade to?

That must be a different problem, surely?

And how did you arrive at that conclusion? Have you reverted the patch
and it works again? I really don't see how this particular patch could
break it since afaict it's entirely correct, there are exactly two tests
for IEEE80211_TX_INTFL_DONT_ENCRYPT in mac80211, both of which execute
before the code I removed.
