Eric Schenk fixed this bug in 2.0.31. It's still in 2.1.x. The
attached test-writev.c program will send three 100byte buffers
using writev() and with a 2.1.x kernel (or 2.0.x x<31) this will
cause three segments to be put on the wire.
Thanks for reminding us about this. I'm currently on the TCP war-path
for 2.1.x, and after I fix the TCP bandwidth bug I'll look into this.
(for those who want to see the current state of affairs in my TCP
tree, checkout a copy the vger CVS kernel sources, ftp to vger
and grab /pub/linux/README.CVS and do what it says. The tree is
also available via http://samba.anu.edu.au/ and there also you can
join a mailing list which gets messages when changes are made to
the vger CVS sources)
Later,
