ath(4) apbridge does not work with PF and ALTQ

Hello,

I found out that "apbridge"ing with ath(4) does not work once I enable
altq on the interface with pfctl on recent CURRENT.

I can communicate between different hosts connected to ath(4) in hostap
mode when altq is not configured and it does not work for any protocol
(even for ARP) when it is enabled.

Now that I found out why it sometimes worked and sometimes not I think
it had not been working for some time - from 6.2 on at least.

>From /etc/pf.conf:
------
int_if="ath0"

altq on $int_if bandwidth 10Mb cbq queue { dflt, mini }
queue dflt bandwidth 1Mb cbq(default, borrow, ecn)
queue mini bandwidth 256Kb
