Extreme Summit48si.

You can do this by changing the ethertype of VLANs, Extreme calls this 
VMAN (9100 for vlans intead of 8100). This requires a network design to 
match. The switch has 48 ports and two SFP gig ports.

It does that.

I dont know about RSTP and MST, but it does the rest. It also has EAPS for 
subsecond L2 failover.
