tweaks and bug fixes by yours truly.
Here's what Denny had to say:
nubus.h:
- add a drsw entry for my card
[ I also added a couple of constants for more display cards ]
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.
