>Description:
When I set promiscus mode on fxp interface, multicast packets
which the host doesn't joined address are not received.
>How-To-Repeat:
set promiscus flag on fxp. tcpdump on the interface and send
multicast packets to not-joined address. they does note been 
observed.
>Fix:
Intel NIC has two flags for promiscus mode, one for unicast and another is for multicast.
When the user set promiscus mode flag on the interface, both flags should be set.
However current code (including -current) set only unicast promiscus flag.
fxp.c on OpenBSD fixed this problem. Please refer and import it.

 Sorry for late response.

 I've confirmed. (actually by my subordinate :)

 Commited patch corrects the problem on fxp I've reported.

 Thanks!
