yes, and forwarding only without pf.
I'm sending traffic from host connected to vlan/ix0 and forward through
em5 to other host.
I'm sending 1Gbps of traffic with cisco t-rex

In setup without vlan on ix I've got only one watchdog at the begging of
testing and that's it.
With vlan I'm getting around 6 or 7 watchdogs per minute which means 6
or 7 links going up/down.
without vlan
smc4# netstat -sp tcp | grep TSO
0 output TSO packets software chopped
268 output TSO packets hardware processed
