Hardware Driver for IBM 4/16 Shared Memory Cards (ISA/EISA)

• /usr/src/sys/i386/isa/if_tok.c
• /usr/src/sys/i386/isa/if_tokreg.h
• /usr/src/sys/i386/isa/if_tokvar.h
• Driver debug output.
• Sample bpf dump from my hacked tcpdump.
• tokenring.tar.gz Most everything for IBM in one file.

It's alive, too!

The IBM driver will finally transmit. It's not pretty. It's not reliable. Hell, it might cause a social disease, but it TRANSMITS!

I wouldn't try to use this for ANYTHING remotely resembling production or maybe even test :) It likely won't last for more than a few minutes at a time.
