ethernet/broadcom: use core min/max MTU checking
tg3: min_mtu 60, max_mtu 9000/1500
bnxt: min_mtu 60, max_mtu 9000
bnx2x: min_mtu 46, max_mtu 9600
- Fix up ETH_OVREHEAD -> ETH_OVERHEAD while we're in here, remove
duplicated defines from bnx2x_link.c.
bnx2: min_mtu 46, max_mtu 9000
- Use more standard ETH_* defines while we're at it.
bcm63xx_enet: min_mtu 46, max_mtu 2028
- compute_hw_mtu was made largely pointless, and thus merged back into
bcm_enet_change_mtu.
b44: min_mtu 60, max_mtu 1500
