  Log:
  Disable TSO support.
  Under certain circumtances, if TSO is active, Yukon II generates
  corrupted IP packets. All corrupted IP packets I noticed were the the
  last segmented packet in a TSO request. The corrupted packet resulted
  in retransmission of the damaged packet which in turn decreased network
  performance dramatically.
  Unfortunately it seems that there is no way to workaround this bug
  as TSO is completely handled in hardware. Disable TSO until we find a
  working workaround or a new silicon revision that doesn't have this
  hardware bug.
