RE: iSCSI CRC: A CRC-checking example

Hi
 For all zeros the value after complementing the CRC result is 0x556c8951.
If it is bit-swapped it becomes  0x8a9136aa.
 
 The way you will get the constant remainder 0x1c2d19ed is that you append
 0x556c8951 and not 0xaa36918a to the all-zero data bytes. The crc-check
engine would assume as if it is processing 4 more bytes. If we bit-swap the
CRC while transmitting, don't we have to again swap it at the receive side
and then pass it through the crc-check engine.
