Valid VLAN ids are 1-4094. VLAN 0 and 4095 are reserved numbers.

>(0x8100), length 60: vlan 0, p 0, ethertype IPv4, 176.65.149.186.40713 > 

The VLAN tag includes the VLAN id and a priority.

A VLAN id 0 is used to tag a packet with only a priority, otherwise
it is supposed to be treated like an untagged packet.

Our vlan driver doesn't handle this itself. Our ethernet code instead
strips the tag and passes the packet through to normal processing.

I don't think that we can send such packets but your uplink
_should_ also accept untagged packets.
