The Intel i82586 and i82596 and can be told to receive frames with a bad FCS.
They can also be told to send a precomputed FCS rather than computing it on
the fly. The i82596 and tulip can also transfer the FCS to memory when
receiving frames. I guess all of this is also supported on the i82557/8/9.
