  Modified files:        (Branch: RELENG_6)
    sys/dev/msk          if_msk.c 
  Log:
  MFC if_msk.c rev. 1.15 to RELENG_6.
    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.
