[Intel-wired-lan] [PATCH net-next] ice: Add support for changing MTU on PR in switchdev mode

[Marcin Szycik]

This change adds support for changing MTU on port representor in
switchdev mode, by setting the min/max MTU values on port representor
netdev. Before it was possible to change the MTU only in a limited,
default range (68-1500).
