I'm not sure that I understand your problem here:
An LSO packet is simply a big packet that the hw should send using
smaller packets.
Assuming that you have a cm connection between the two endpoints, is
there any reason not to send this packets using CM?
One possibale reason that I can see is checksum: For LSO packets windows
will not calculate the regular checksum but rather do some calculation
of the pseudo header checksum. But I guess that this is part of the
problems that we have with checksum and connected mode in any case.
Thanks
