[ofw] enabling LSO causes IB_INVALID_PARAMETER in ib_post_send() ?

[Smith, Stan]

Hello Alex,
  Using the SVN head of ipoib_ndis6_cm\ I find when running a checked version which has LSO enabled per .inf file mod, (ttcp -t to a winOFED 2.5 installed system), the ipoib_process_sg_list_real() call to ib_post_send() call ALWAYS returns IB_INVALID_PARAMETER?

If I change the .inf file to disable LSO, and reload ipoib.sys, ib_post_send() always succeeds.

HCA is Infinihost MT25208 with latest firmware.

Any thoughts as to why LSO enabled produces the ib_post_send() error in this config?
