OK, I'm confused if ether_ioctl() internally calls driver_init() at
ENETRESET case.

ENETRESET is only used for multicast filter for ethernet drivers, AFAIK.
And you can see similar code in several drivers, which mostly written
by Jason.

Anyway, there are some bugs around promisc mode for an driver.  But
I have a difficulties to sync with my working code, which is modified
to support LEAP for Aironet 350 series, and worse, running on NetBSD 1.5
to work with vmware...
