Hi,


The new RSTP code I have been working on has more info that can be shown
and tweaked by the network admin when setting up the layer2 topo. I now
have the problem of what utility to stuff it into.

  a) ifconfig
  b) netstat
  c) some new util like bridgestat

I realise that ifconfig is for setting the interface config and should
not be abused. I am tempted to add a new util, here is an example of
what I need to show.

  ...

Interface 2

Any suggestions?
