Hang up/down re0: <D-Link DGE-528(T) in promisc mode

[Prokofiev S.P.]

I have a problem on FreeBSD 6.2-STABLE with NIC D-Link DGE-528(T).
When I put interface into promiscuous mode or output by tcpdump or simply
ifconfig xxx promisc/ifconfig xxx -promisc, the NIC hang down and then hang up.
This is not normal behaviour...
Sorry for my English.
