I’m running an Orin on a CTI Forge carrier that has 4 Ethernet ports. I have two of the Ethernet ports bridged together with the WiFi card. When I do that, however, the MTU on the bridged Ethernet ports drops to 1466, which causes problems with any two devices communicating through the bridge. To remedy this, I added a pre-up clause in the /etc/network/interfaces, to set the MTU of the bridged ports to 1534 like so
pre-up ip link set dev eqos0 mtu 1534
But I get this error, and then sometimes the bridge doesn’t come up:
