42 * The RSK board has the SMSC9118 wired up 'incorrectly'.
43 * Byte-swapping is necessary, and so poor performance is inevitable.
44 * This problem cannot evade by the swap function of CHIP, this can
45 * evade by software Byte-swapping.
46 * And this has problem by FIFO access only. pkt_data_pull/pkt_data_push
47 * functions necessary to solve this problem.
