cant get bridgeing on iwi to work

[Johan Johansen]

My Soekris 4501 is running FreeBSD 6.0-RELEASE and is equipped with
Intel wireless 2915a/b/g-card in the PCI-slot. The driver is
iwi-firmware-2.4_2 from ports.

This works ok as a router, but bridgeing through iwi0 wont work.
Actually, tcpdump show me that the data is leaving the iwi0, but
they are not.

iwicontrol tell me that "Number of transmission failures" is increased
by 1 for each packet trying to leave the interface.

Shouldnt this work?
