- switch all interrupt functions to an int (*)(void *) prototype.
- do not register dummy functions for all unhandled interrupts, instead
let the dispatchers cope with NULL.
- add evcount interrupt counters.

more hardware support.

sonic_get is faster and simpler.
sn_ioctl works like other current ether drivers now.
Sync up with netbsd to ease maintenance; incorporate some "gratuitous" formatting changes so I won't have to do two totally seperate mods each time.

about his SONIC-T LC/PDS card.

Change in the way receive buffer areas are handled. Before we gave
the chip 16 buffers, each 1536 bytes (big enough for one packet).
Now we're handing the chip 8 buffers, each 4 Kbytes, and letting
the chip fit as many packets as it can in each one. This should
help keep it from running out of buffer space. Also make some of
the performance-crucial routines inline. It made no measurable
difference except to make me feel better

Denny says:
if_sn.c:
- allocate sc->space using malloc (Scott wanted this).
- make csr accesses use NIC_PUT/GET, remove sc->sc_csr.
- add multicast and IFF_PROMISC support. multicast isn't
well tested, but I made sure the unicast case still
works.
- finish the new arp interface, remove sc->sc_enaddr
if_snreg.h:
- remove struct sonic_reg
if_snvar.h:
- add NIC_PUT and NIC_GET macros a la if_ae
- remove sc_txhead, it isn't used.
if_sn_nubus.c:
- clean up support for my SE/30 card.
- Move add_nubus_intr from if_sn.c (to keep if_sn.c MI)
if_sn_obio.c:
- make Q610, C610, Q650, C650, Q800 use EXBUS.
- PB500 had a "return" where "break" was intended. PB500
probably wasn't working.
- move add_nubus_intr from if_sn.c.
- add an "explanation" why Apple's ethernet addr is encoded
in token ring format in the PROM.

Much hacked by me to merge and partially busify.
Add code that I lost a while back for digging the proper mac address for
internal ethernet.
Still needs work, but checkpointed--works at least as well as the last
version.
