Change the MTU Permanently (Oracle Solaris)

1. Add this line in the /etc/driver/drv/i40e.conf file:

   default_mtu = desired-frame-size
   

   where desired-frame-size value can range from 1500 to 9706.

2. Reboot the server.
3. Another way to change the MTU permanently is with # dladm set-linkprop -p mtu=9706 net0.

   # dladm set-linkprop -p mtu=9706 net0
