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 __________________________________________________________________ Get your own FREE, personal Netscape Webmail account today at http://webmail.netscape.com/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
