We have a fleet of xavier nx and agx orin devkits.
After flashing the device, we configure the network port with a /mnt/boot/system-connections/local file:
[connection] id=local type=ethernet interface-name=eth0 permissions= secondaries= [ethernet] mac-address-blacklist= mtu=8192 [ipv4] dns-search= method=shared [ipv6] addr-gen-mode=stable-privacy dns-search= method=auto
After reboot, this file is copied to /etc/NetworkMamager/system-connections/local and works correctly, but the MTU is not set to 8192. This used to work in previous versions.
How can we fix this?
