I am tearing my hair out trying to figure out why I an unable to set the
MTU of an OVS port with a .link file.
I am trying to create this:
+----------------+ +----------------+
| | | |
| eno1 | | eno2 |
| (MTU = 8996) | | (MTU = 8996) |
| | | |
+-------+--------+ +-------+--------+
| |
+-------------------+-------------------+
|
+-------+--------+
| |
| bond0 |
| (MTU = 8996) |
| |
+-------+--------+
|
+-------+--------+
| |
| ovs0 |
| (MTU = 8996) |
| |
+-------+--------+
|
+-------------------+-------------------+
| |
+-------+--------+ +-------+--------+
| | | |
| vlan248 | | vlan250 |
| (MTU = 8996) | | (MTU = 1500) |
| | | |
+----------------+ +----------------+
Everything works, except that vlan250 is inheriting the jumbo MTU from
ovs0. I've created a link file to set the MTU to 1500:
/etc/systemd/network/98-vlan250.link:
[Match]
OriginalName=vlan250
[Link]
MTUBytes=1500
For some reason, this isn't working.
I've set udev_log="debug" in /etc/udev/udev.conf and rebuilt my
initramfs. I've also created a drop-in for systemd-networkd that sets
SYSTEMD_LOG_LEVEL=debug.
A full boot log with these settings can be found at:

Any ideas or debugging techniques very much appreciated.
