Hi,
This is with reference to the mbuf structure widely used in freeBSD networking code.

When a packet is received with a multicast MAC address, the ether_input function sets the multicast flag to the mbuf. But i found that it is nowhere used in the netinet6 directory modules.

Can any body inform me why there is a need to set this flag? I feel that there is no need since a multicast MAC address is always associated with a multicast ip address.

regards
ravi prasad
