Simplify checksum offload test based on chip revision.

Comment out RX checksum code for really lame 82559 chip.
It's probably better to have stack handle that, rather
than faking it by manually.

Fix and enable small packet copy to mbuf.  Packets smaller
than MHLEN (eg. TCP ACK) are copied into a new mbuf.  The
cluster can stay in the RX DMA ring and get reused instead
of wasted on a very small packet.

Tested on 82559 (A0) and 82550 (C) though it does sometime
wedge in a very weird way.  A up/down cycles clears it again.
