per-route TCP windows?

[Mark Hahn <hahn@xxxxxxxxxxxxxxxxxxx>]

I was recently fiddling with TCP performance on long-fat links,
and noticed that iproute2 seems to allow one to set a per-route window.

is this implemented in the stack?  I gave it one try and it didn't
seem to work, but I admit I haven't delved into the code yet.

we'd like to tune for some 10Gb, 3-6 ms links, mainly to move large files
between our sites.  this is not CERN-scale stuff, but being able to configure
large windows on particular routes sounds terribly convenient...

thanks, mark hahn
