NAT: TCP MSS clamping
NAT plugin changes the MSS value in TCP SYN packets to avoid fragmentation. If the negotiated MSS value is greater than the configured value it is changed to the configured value. If the negotiated MSS value is smaller than the configured value it remains unchanged. Change-Id: Ic3c4f94a2f1b76e2bf79f50f3ad36a4097f3f188 Signed-off-by: Matus Fabian <matfabia@cisco.com>
