I fully agree with Steve. The netgraph code is ideal to handle the vlan stuff.

I've dig a bit into code and found that to get such mechanism working it need to add ng_iface node hook to inject not demuxed frames. And fix a bit code related to ARP. > - Steve -- TSB Russian Express, Moscow Vladimir B.
