ethernet: use core min/max MTU checking
et131x: min_mtu 64, max_mtu 9216
altera_tse: min_mtu 64, max_mtu 1500
amd8111e: min_mtu 60, max_mtu 9000
bnad: min_mtu 46, max_mtu 9000
macb: min_mtu 68, max_mtu 1500 or 10240 depending on hardware capability
xgmac: min_mtu 46, max_mtu 9000
cxgb2: min_mtu 68, max_mtu 9582 (pm3393) or 9600 (vsc7326)
enic: min_mtu 68, max_mtu 9000
gianfar: min_mtu 50, max_mu 9586
hns_enet: min_mtu 68, max_mtu 9578 (v1) or 9706 (v2)
ksz884x: min_mtu 60, max_mtu 1894
myri10ge: min_mtu 68, max_mtu 9000
natsemi: min_mtu 64, max_mtu 2024
nfp: min_mtu 68, max_mtu hardware-specific
forcedeth: min_mtu 64, max_mtu 1500 or 9100, depending on hardware
pch_gbe: min_mtu 46, max_mtu 10300
pasemi_mac: min_mtu 64, max_mtu 9000
qcaspi: min_mtu 46, max_mtu 1500
- remove qcaspi_netdev_change_mtu as it is now redundant
rocker: min_mtu 68, max_mtu 9000
sxgbe: min_mtu 68, max_mtu 9000
stmmac: min_mtu 46, max_mtu depends on hardware
tehuti: min_mtu 60, max_mtu 16384
- driver had no max mtu checking, but product docs say 16k jumbo packets
are supported by the hardware
netcp: min_mtu 68, max_mtu 9486
- remove netcp_ndo_change_mtu as it is now redundant
via-velocity: min_mtu 64, max_mtu 9000
octeon: min_mtu 46, max_mtu 65370
