CAUTION:
■ You cannot enable both broadcast suppression and multicast suppression
simultaneously on the same card. Namely, once you have enabled broadcast
suppression on some ports of a card, you cannot enable multicast suppression
on the other ports of the card, and vice versa.
■ If multicast suppression is enabled, broadcast packets are also suppressed at
the same time, while broadcast suppression does not work on multicast
packets.
