I definitely agree that it is a good investment, especially considering that I am doing this all the times when i port FreeBSD stuff to linux... The linux version of netmap, which i just completed, was mostly done playing tricks to remap struct ifnet to struct net_device... cheers luigi _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
