[pve-devel] [PATCH pve-network] add vnet vlan-aware option
Alexandre Derumier

Mon May 25 15:03:23 CEST 2020
Some users would like to be able to defined vlans at
vm level, or allow trunks, on top of already
tagged vnet. (including vlan on top of vxlan tunnel)
Allow it on all layer2 plugins, and add a warn
for evpn layer3 plugin.
