Make hardware generate 802.11 sequence numbers (except for unicast
QoS data frames) such that the same counter is used for beacons,
management frames and non-QoS data frames.
This will help clients that don't like jumps in sequence numbers,
like the FreeBSD duplicate detection code.
Found after an interesting discussion with Yao Zhao.
