+1 obviously. Your refusal to debug this any further does not put 
nVidia's TCP / NVMe offload in a good light. On one hand you
claim to have TCP experts in house and are pushing TCP offloads and
on the other you can't debug a TCP issue for which you reportedly 
have an easy repro? Does not add up.
