if the link-level address has been initialized already.
The majority of modern drivers never does this and works fine, which
makes me think that the check is totally unnecessary and a residue
of cut&paste from other drivers.
This change is done to simplify locking because now almost none of the
drivers uses this field. The exceptions are "ct" "ctau" and "cx"
where i am not sure if i can remove that part.
multicast hash are written. There are still two distinct algorithms used,
and there actually isn't any reason each driver should have its own copy
of this function as they could all share one copy of it (if it grew an
additional argument).
crashes that had sn0 as the irq that's being serviced, when there was
no sn0 in the system. This seems to prevent them. Also, we want to
wait until after we've registered with the network layer before we
turn on the interrupt spigot to avoid races.
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.
This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

possible to have different probe/attach semantics between the two
systems and yet still use the same driver for both.
Compatibility methods for OLDCARD drivers. We use these routines to make
it possible to call the OLDCARD driver's probe routine in the context that
it expects. For OLDCARD these are implemented as pass throughs to the
device_{probe,attach} routines. For NEWCARD they are implemented such
such that probe becomes strictly a matching routine and attach does both
the old probe and old attach.
compat devices should use the following:
/* Device interface */
DEVMETHOD(device_probe), pccard_compat_probe),
DEVMETHOD(device_attach), pccard_compat_attach),
/* Card interface */
DEVMETHOD(card_compat_match, foo_match), /* newly written */
DEVMETHOD(card_compat_probe, foo_probe), /* old probe */
DEVMETHOD(card_compat_attach, foo_attach), /* old attach */
This will allow a single driver binary image to be used for both
OLDCARD and NEWCARD.
Drivers wishing to not retain OLDCARD compatibility needn't do this.

The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing

Add support, kinda, for megaheartz xjack nic cards. This support
works well for one machine per ethernet segment because it hard codes
the MAC address. The pccardd in -current doesn't have support to
parse the ethernet address from the CIS in the funky way that the
megaheartz card does things (it includes it in the info tuple, as
ascii, which is non-standard). I'd rather kludge this for the moment
and work to read the CIS from the kernel rather than mess with
pccardd.
The isa attachment is untested. The pccard attachment is known to
work since I'm committing over it.
