This adds support for the SiS intergrated NIC on some Athlon64 motherboards.
The MAC address is stored in the APC CMOS RAM and this fixes the
sis driver ending up with a 00:00:00:00:00:00 MAC address.

following drivers: bfe(4), em(4), fxp(4), lnc(4), tun(4), de(4) rl(4),
sis(4) and xl(4)
More patches are pending on: http://peoples.freebsd.org/~mlaier/ Please take
a look and tell me if "your" driver is missing, so I can fix this.

this driver by introducing a flag saying we already stopped the device.
On my Soekris net4801, this took a ping -i 0.001 from spending 80% of
time in interrupt handling to 10% (approx numbers).
This was a particular problem for the net4801 because the tree
interfaces share the same interrupt, but it would be a problem for
any configuration where an unused if_sis interface shares an interrupt
with a busy device.
Other drivers may have similar problems.

Only do short-cable on revisions that need it.
Move generic initialization before short-cable fix, in order to not
clobber short cable fix register setting.
the packets are immediately returned for sending (e.g. when bridging
or packet forwarding). There are more efficient ways to do this
but for now use the least intrusive approach.

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).
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.

We can't update the device description in attach (why not ?), so
we device_print() what we find.
Conditionalize the short cable fix on this being older than rev 16A.
Call device_printf() when we apply short cable fix.
Include interrupt hold-off setting for rev 16+ under "#ifdef notyet"
The device_printf()'s will go under bootverbose once the various
issues have settled a bit.
