That change was introduced by me. I guess the root cause of the problem was long initialization time of hardware which in turn resulted in unbearable boot time when multiple-alias addresses are assigned to em(4). I don't remember details,though. Since we're in the release cycle, the change you suggested would be quick fix for 8.0. I think em(4)/igb(4) should remove SIOCSIFADDR handling in driver which is layering violation. _______________________________________________ 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"
