Ordinary, STP.  The 2.6.22 kernel will have all the bits to run STP in
user mode, and there is a version of RSTP in userspace see:

The RSTP code uses the rstplib and it knows about VLAN's, but the hooks
aren't there yet. Eventually, full MSTP 802.Q seems like a good idea.

Someone had sent some patches to do PVST, but PVST seems to be Cisco
centric. and the patched version was too inflexible, so I didn't put
it in mainline.
