ethernet/marvell: use core min/max MTU checking
mvneta: min_mtu 68, max_mtu 9676
- mtu validation routine mostly did range check, merge back into
mvneta_change_mtu for simplicity
mvpp2: min_mtu 68, max_mtu 9676
- mtu validation routine mostly did range check, merge back into
mvpp2_change_mtu for simplicity
pxa168_eth: min_mtu 68, max_mtu 9500
skge: min_mtu 60, max_mtu 9000
sky2: min_mtu 68, max_mtu 1500 or 9000, depending on hw
