http://perforce.freebsd.org/chv.cgi?CH=124733 Change 124733 by zec@zec_tpx32 on 2007/08/05 16:15:25 When detaching an ifnet clear its if_vnet field, so that we know it's a homeless entity until it gets reattached. Do not announce ifnet events to devctl/devd, except for ifnets attached to the default vnet (vnet_0).
