Doh! My patch is the same as the current code :)
What we need to do is to remember mss_now across sendpage calls.
Luckily the value of truesize lets us deduce the value of mss_now.
To complicate the picture the mss might have been reduced between
sendpages calls. So we take the minimum of the remembered mss
and the current mss.
Any brave souls out there to try this?
