33 * The RSK board has the SMSC89218 wired up 'incorrectly'.
34 * Byte-swapping is necessary, and so poor performance is inevitable.
35 * This problem cannot evade by the swap function of CHIP, this can
36 * evade by software Byte-swapping.
37 * And this has problem by FIFO access only. pkt_data_pull/pkt_data_push
38 * functions necessary to solve this problem.
