smarter fdb timeout scheme
slab cache for fdbs?
I'm not happy with the current timer tick interval
make the bridge device zerocopy/highmem transparent
move the spanning tree code to userspace
to be MLT (Nortel Multi Link Trunking) compatible: send bpdu's on all
  interfaces in the bonding bundle
faster switch to forward mode
  per-port STP disabling
  'fast start': listening->learning->forwarding in 2*hello instead of 2*fd
enslaved devs same MAC (like tap), then one changes
