[pve-devel] [PATCH pve-common V2 1/4] INotify : add uplink-id option

uplink-id is an integer

it's used to abstract the interface name (could be different on differents hosts)
and map it to a transportzone.

uplink-id is only allowed on physical interfaces (bond,eth,vlan)
as it's used for traffic to external

example:

auto eth0
iface eth0 inet manual
        uplink-id 1
