Linux LLC Stack Origins  The stack present on the Linux kernel
was originally contributed by Procom Inc, that released a
combined NetBEUI + LLC stack developed for Linux 2.0.36.  Alan
Cox suggested that since Arnaldo Melo had time to work on things
like IPX he should consider taking a stab at porting Procom's
NetBEUI stack to 2.4, which he did, getting samba + netbeui +
LLC + Linux mostly working.  Jay Schullist, the Linux-SNA
project hacker also was working on another LLC stack but since
Procom's was more well tested he switched to Procom's stack and
contributed the initial BSD Sockets layer for the LLC protocol
family, PF_LLC.  to be continued
