Hmm, I was drunk I think, my bad. Have no idea where TSE came from, I
meant TSO I believe

That being said, TSE could mean "TCP segmentation Enable "

See

I see.  I was under impression TSO and TOE are the same thing. I was
therefore nervous that enabling TSO would have triggered the problems
discussed on the kernel mailing list

Actually, it would not have been fun moving to IPv6   if TOE had taken
off as I believe that would have meant replacing the NIC cards,

Thanks a lot Len
