I came across a packet trace with Retix spanning tree packets in it.
So here is a quick hack at a dissector for it.
Several fields are not decoded but maybe someone knows what they are?

It uses llc.dsap && llc.ssap == 0x80,
Those are listed as "XNS" - and I've seen a capture with Token Ring packets with those DSAP and LSAP values containing what appears to be SMB traffic - perhaps some SMB-over-IPX variant? 

Perhaps there's some way to distinguish between those two?
