  SVN rev 188360 on 2009-02-09 01:55:30Z by yongari
  
  MFC r183346
    Add another hardware bug workaround for Yukon II controllers that
    have hardware ram buffer. The silicon bug seem to be triggered by
    pause frames if receive buffer is not aligned on FIFO word(8 bytes).
    To workaround the issue, make sure to align Rx buffers on 8 bytes.
    Unfortunately this workaround requires yet another Rx fixup for
    strict alignment architecture machines to align IP header.
  
    For newer hardwares that lacks ram buffer may not have this bug so
    check number of available ram buffer size to see the existence of
    ram buffer.
