    MAC prefix for each vnet

    setting mac on vnet could be only usefull if you have an ip on the vnet. (so mainly when vnet is used as gateway for the vms). It's only possible with evpn, as the ip/mac is the same on each vnet (anycast ip). Don't make sense to add feature for other zone type. if really needed, you can...
