MTU limited to 10000
Hello,
I am trying to configure my interface to a MTU of 65522, for thunderbolt ethernet, but it seems to be limited to 10000 unless I configure the interface manually or without NetworkManager.
The reason for setting this high MTU is to get a more stable 10Gbit connection between the nodes, any less is causing jitter and slightly higher CPU usage.
This is also a problem with Infiniband which typically are configured in connected mode with MTU of 65520. (Some Red hat infiniband documentation)
I don't understand why the MTU is limited to 10000 in my NetworkManager, and I'd appreciate any help in fixing this.
