freebsd-dev/contrib/tcpdump/interface.h
Julian Elischer 722012cc0c World, I'd like you to meet the first FreeBSD token Ring driver. 
This  is for various Olicom cards. An IBM driver is following.
This patch also adds support to tcpdump to decode packets on tokenring.
Congratulations to the proud father.. (below)
