New ath code on AP: strange client behavioir

[Lev Serebryakov]

Hello, Freebsd-wireless.

 I've  build  new  image for my router (r240742), and now traffic stuc
 shortly after client association.

 After manual re-assotiation (diconnect/connect cycle) traffic stuck
 after several packets (2-3MiB of traffic) again.

 According to tcpdump on AP, it sees some traffic from client, and
 send something back, but client could not resolve any name, etc...

 Even more, it looks like, tcpdump sees last fiew packets from client
 multiple times, because at moment when client could not do anything,
 tcpdump SOMETIMES shows latest MCAST UDP traffic from client
 (Microsoft network) over and over again!

 AP is AR9220, 802.11gn mode.

 Client is Intel Advanced-N, but in 802.11g only mode.
