bridge: I wish there was decent documentation on how to configure & use Linux's vlan-aware bridge functionality ('bridge vlan' command). I understand it means that you don't have to create separate vlan interfaces but I've never found decent documentation on how to configure it.

macvlan: is VEPA mode still a thing that people use, or did it not take off (in terms of switches that support it--last time I looked I didn't find anything newer than about 10 years old that talked about VEPA but maybe I suck at searching?)

macvlan: 'bridge' sounds really convenient, if you try it you'll find that the host can't communicate with macvtap interfaces.

macvtap: does this suffer from the same limitation as macvlan in 'bridge' mode (host can't communicate with mactvap interfaces?
