Description of problem:

From RDS feedback:

This needs written as a procedure:

To change the MTU value of a virtual function after the pod has started, do not configure the MTU field in the SriovNetworkNodePolicy CR. Instead, configure the NmState Operator or use a custom systemd script to set the MTU of the physical function to an appropriate value. For example: #ip link set dev <physical_function> mtu 9000 

TBH not sure about custom script guidance here I guess we should find out how to use NmState Operator
