The "driver" from linux-sna is the code I'm working on (based on code donated
by Procom, inc) that nowadays sits in net/llc in 2.5, IOW, its the same code.
I'm still doing lots of modifications on the net/llc code, as I'm still not
satisfied with the socket locking mess that is there because the
net/llc/llc_sock.c (llc_ui, PF_LLC, BSD sockets interface with userlevel) is
using a struct sock and the core is using another, but now that I'm back from
vacation I'm working on fixing this, making it look a lot more like the tcp/ip
codepaths in the kernel, so, if you are interested in going in this direction,
I'm interested in test results, etc.

Maybe adapting the XOT code to do userspace X.25 over a PF_LLC socket could
do it :)
