ddstreet's ppa included a hotfix for this which was installed on Cust lab MAAS region controller. A machine was deployed which included a subnet defined with MTU 9202 and two NICs in a bond. After deployment, the bond showed MTU 9202 (used ifconfig), and the /e/n/interfaces file was coded in a way that a manual reboot preserved the MTU 9202 setting for the bond.
