Hi:

Kernel 2.1.126:

In <net/tcp.h> :: tcp_select_initial_window() I see the following:

        /* NOTE: offering an initial window larger than 32767
         * will break some buggy TCP stacks. We try to be nice.
         * If we are not window scaling, then this truncates
         * our initial window offering to 32k. There should also
         * be a sysctl option to stop being nice.
         */

However, I can't seem to find the sysctl to "stop being nice."  What is the
procedure to allow a large (scaled) initial window?  I don't know the stack
code too well, but it looks like there's more to it than just adjusting the
few lines following the above comment.

Thanks.
