Real bridges run current newwer Spanning Tree Protocol that converges faster.
The current Linux STP code is on older standard (around 2001). The current STP
standard use RSTP which converges much faster.
http://en.wikipedia.org/wiki/Spanning_Tree_Protocol
There is a userspace RSTP daemon that almost nobody uses.
There are a number of other STP enhancements that are needed like
STP protection and MSTP, as welll as the Cisco non-standard STP VLAN stuff.
Fixing STP and testing it is a fairly project, too big for a spare time
effort and currently not something high enough on the project chart for me to
be able to dedicate much company time on. Contributions welcome.
