Subject: tcp: use TCP_DEFAULT_INIT_RCVWND in tcp_fixup_rcvbuf()
X-Git-Tag: v3.2-rc1~182^2~42

tcp: use TCP_DEFAULT_INIT_RCVWND in tcp_fixup_rcvbuf()

Since commit 356f039822b (TCP: increase default initial receive
window.), we allow sender to send 10 (TCP_DEFAULT_INIT_RCVWND) segments.

Change tcp_fixup_rcvbuf() to reflect this change, even if no real change
is expected, since sysctl_tcp_rmem[1] = 87380 and this value
is bigger than tcp_fixup_rcvbuf() computed rcvmem (~23720)

Note: Since commit 356f039822b limited default window to maximum of
10*1460 and 2*MSS, we use same heuristic in this patch.
