[pve-devel] [PATCH v5 manager] ui: vm network: allow to override MTU for virtio devices

[Oguz Bektas]

we already have the 'mtu' option in the API, so we can just expose
that option inside the 'Advanced' menu for virtio network interfaces.

v4->v5:
* changed default mtu from 1500 to empty (dominik's review on v4 caught
a small bug where the mtu would be set to 1500 even without showing the
advanced fields)
