Log message:
some re(4) chips can do jumbos, but none of them can checksum jumbo
packets.
rather than disable cksum offload for all packets, this sets things
up so we still advertise offload to the stack, but if the driver
gets a large packet it does the checksum itself in software.
small (normal sized) packets still get offloaded like now. if you're
doing a jumbo you'll be doing the cksum in software, but will
hopefully win overall cos you'll be doing a 6th of the work cos
you're doing more data in every packet.
