Documented steps
Use a dotted parent name so Docker auto-creates the 802.1Q VLAN sub-interface, e.g. docker network create -d macvlan --subnet=192.168.50.0/24 --gateway=192.168.50.1 -o parent=eth0.50 macvlan50 (VLAN 50).
Attach containers; their traffic is tagged with VLAN 50 at the interface.
Verify the sub-interface appears (ip link) and that packets carry the VLAN tag.

Known gotchas
The sub-interface is created on the fly; docker network rm deletes sub-interfaces Docker created but never the physical parent interface.
The upstream switch port must be configured for trunking on the VLAN, otherwise tagged traffic is dropped.
