NETGRAPH- bridge vlans using netgraph help

[Abdullah]

Configuration style doesn't really matter. I am trying to figure out how to
make tagged traffic talk in  a bridge. I have always had good support from
bsd people over the last 4 5 years since i started using it, maybe it's
time to add something to it :)
What gives me hope is that linux (cumulus linux, openswitch, ONL) are doing
so, i dont see why BSD can't do it. I haven't searched much other bsd
flavors though.

Regards
Abdullah
