  SVN rev 193294 on 2009-06-02 04:35:44Z by yongari
  
  Add frame parser capability of Yukon FE+ and Yukon Extreme. With
  this feature hardware automatically computes TCP/UDP payload
  offset. Introduce MSK_FLAG_AUTOTX_CSUM to mark the capability.
  Yukon Extreme B0 revision is known to have a silicon for the
  feature so disable it. Yukon Extreme B0 still can do Tx checksum
  offloading but CPU have to compute TCP/UDP payload offset. To
  enable traditional checksum offloading, disable automatic Tx
  checksum calculation capability.
  Yukon Extreme A0 revision could not use store-and-forward mode for
  jumbo frames(silicon bug) so disable Tx checksum offloading for
  jumbo frames.
  
  I believe controllers that have MSK_FLAG_AUTOTX_CSUM capability or
  new descriptor format do not have Tx checksum offload bug so
  disable checksum offloading workaround for for short frames.
