After RTFM-ing well I learned that tcpdump and wireshark work perfectly. This
bugreport was because of my ignorance. See man tcpdump:
vlan [vlan_id]
True if the packet is an IEEE 802.1Q VLAN packet. If
[vlan_id] is specified, only true if the packet has the specified
vlan_id. Note that the first vlan keyword
encountered in expression changes the decoding offsets for the remainder of
expression on the assumption that the packet is a VLAN
packet. The vlan [vlan_id] expression may be used more than once, to
filter on VLAN hierarchies. Each use of that expression
increments the filter offsets by 4.
For example:
vlan 100 && vlan 200
filters on VLAN 200 encapsulated within VLAN 100, and
vlan && vlan 300 && ip
filters IPv4 protocols encapsulated in VLAN 300
encapsulated within any higher order VLAN.
