Hi In my seemingly never ending quest to get a correctly functioning driver for the WebGear wireless LAN cards I need some advice on how to DTRT with multi-casts. The WebGear cards can be programmed with 16 multicast addresses, from these the NIC itself generates hashes. So what should I do when there are more than 16 mutli-cast addresses? Some drivers appear to set ALLMULTI, others set a promiscuous mode. Some of the promiscuous mode drivers do some filtering before sending packets to BPF/ether_input and other don't. What should I do when I see ALLMULTI? Help! Thanks, Duncan --- ________________________________________________________________________ Duncan Barclay | God smiles upon the little children, dmlb@ragnet.demon.co.uk | the alcoholics, and the permanently stoned. ________________________________________________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
