Re: [pve-devel] [PATCH v3 manager] ui: vm network: allow to override MTU for virtio devices

["DERUMIER, Alexandre" <Alexandre.DERUMIER@groupe-cyllene.com>]

Note that mtu=1 is a special value, it's inherit from the current
bridge mtu value.
(I don't known if it's possible to add some kind of message in the gui
when this value is choose ?)

Thanks for this patch, It's really usefull for vxlan network.
