If you examine the driver source for the Intel Eitherexpress you will see that
MULTICAST hasn't been implemented! ;-)

In any case, the EE16 won't support sustained high-volume traffic, the driver
is too fragile.  Short bursts are OK.

Your card is probably configured wrong, see the installation notes on
configuring the Intel card.  Also, these cards are known to have unpredictable
behavior under FreeBSD.  I never had a problem with them, but there have been
lots of posts from people who did.
