When running tests over higher speed links, the new 2.6 Dynamic Receiver Sizing

clamp restricts the allowed window to the socket receive buffer size (85k)

Easiest fix is to not restrict window clamp if we want to dynamic receiver stuff.
This is what web100 did.

Thanks to John Heffner for finding this.

This turns off all tcp_app_win semantics, are you sure that
tcp_app_win makes no sense when doing dynamic receive buffer
sizing?  I think we should still factor it in, perhaps dynamically,
during rcvbuf growth.
