Bug Description
On a fresh installed Ubuntu bionic, I'm not able to change the MTU of a network interface with netplan. The netplan .yaml looks like the following:
-------
network:
version: 2
renderer: networkd
ethernets:
enp0s3:
addresses:
- 172.30.100.100/16
gateway4: 172.30.1.1
nameservers:
addresses: [172.30.1.1]
mtu: 9000
-------
Manual MTU change with ifconfig works as expected.
