Flaky connection on b43

Flaky connection on b43

[Michael Buesch]

The connection is pretty flaky in b43 on wireless-testing.
There seems to be some rekeying issue. See the log below and notice
the dropped packets after the rekeying.
Note that I have a short rekeying interval on my AP, so rekeying happens often.
Any ideas? Possible bug in mac80211? Does somebody see this with other hardware?
