tcp: fix tcp_grow_window() for large incoming frames
[ Upstream commit 4d846f02392a710f9604892ac3329e628e60a230 ]
tcp_grow_window() has to grow rcv_ssthresh up to window_clamp, allowing
sender to increase its window.
tcp_grow_window() still assumes a tcp frame is under MSS, but its no
longer true with LRO/GRO.
This patch fixes one of the performance issue we noticed with GRO on.
