Eric, Neal, looks good?

The min rtt thing in tcp_tso_autosize() helps a bit but if the sender 
gets congested for a longer stretch min_rtts on new connections are 
high and we're back to sending small TSO, keeping the sender overloaded.
Which is to say - I _hope_ this also solves some of Meta's problems :)  
Ugh, I didn't see the Sashiko report, it's only CCed to the author and bpf@, not to netdev :/

The zero-check sounds legit. Let's revisit this after the merge window.  
Thanks for the comment, I will take action after the merge window.

And, please correct me if I am wrong, the next eligible submission is expected from 30-June, right?
