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.
