Wouldn't it bet better to have the driver detect this (if possible) and
not pass the frame to ether_input at all? If the hardware does not tell
the driver, it should still know the maximum size and do this check
better.

I don't see how the ethertype relates to this check - if at all the vlan
or jumbo frame capabilities of the NIC should count.
