So, instead of calling VLAN_INPUT_TAG, the packet is forwarded to ether_input() with ETHERTYPE_VLAN (0x8100) ? Will this allow me to capture all VLAN information into netgraph's ng_ether and so some processing there. The reason for this is a need to handle a few hundred VLANs, but I read some comments that the chip support only 64 hardware VLANs. I do not any documentation on the chip so any help is appreciated. rgds,
