Some people have sign extension problems. Right now those are getting
pretty rare (they were almost entirely DOS stacks). Dave's call but I dont
have a problem with taking that one out for 2.2
I'm not making this change.
If you want large windows talk to a host who speaks window scaling,
this is what it's there for. Otherwise all bets are off for >32k
windows. (I have real life experience with the sign extension
problems, I did try to enable 64k windows without scaling by default
once and I hit too many machines which wouldn't talk to me properly)
It's getting too close to the 2.2.x wire now for these sorts of itty
bitty things, let's work on the higher priority problems instead so we
can get a clean stable release out soon.
(I'm soon going to be asking people to start reporting TCP performance
and behavior anomalies to me again, I just submitted a sync-up patch
to Linus with all my latest networking fixes etc. so when he releases
a kernel with that stuff in there, fire away)
Later,
