NetBSD 1.0 on generic i386 hardware
System: NetBSD tantrum.frcs.alt.za 1.0 NetBSD 1.0 (TANTRUM) #7: Tue May 2 18:46:12 EST 1995 paul@tantrum.frcs.alt.za:/usr/src/sys/arch/i386/compile/TANTRUM i386

>Description:
CAP (Columbia Appletalk Package) requires SIOCGIFADDR to obtain the
ethernet address of any interface it uses.  It also needs to set 
multicast operation of the interface via the BPF device.
>How-To-Repeat:
>Fix:

2) Minor hacks to the NetBSD kernel:
   * tweak "if_ed.c" to recognise SIOCGIFADDR -- this will need to
     be put into other ethernet drivers
   * tweak to "bpf.c" so that the Bezerkely Packet Filter passes
     multicast ioctl()s on to the driver.  I've not looked at the
     other ether drivers, but if_ed (WD et al) supports multicast,
     hence Appletalk Phase 2.
   These may well not be needed for NetBSD-current, but I've not got
   the time to upgrade (yet), and many others will no doubt want to 
   stick with -1.0.
