This is actually not the case. The ioctl that ifconfig is stuck issuing
is SIOCGLIFFLAGS, as the SIOCSLIFNAME has already succeeded and
returned:
> db5a5cc0::print struct strioctl
{
ic_cmd = 0xc0786975
ic_timout = 0xffffffff
ic_len = 0x4
ic_dp = 0xdb5a5e68
}
0xc0786975 is SIOCGLIFFLAGS. Still scratching my head...
