This behaviour is later broken by commit 843f4a55e (tcp: use tcp_v4_send_synack on first SYN-ACK), as snt_synack is now updated even if tcp_v4_send_synack fails. Also, commit 3a19ce0ee (tcp: IPv6 support for fastopen server) misses the required IPv6 updates for 016818d07. This patch makes sure that snt_synack is updated only when the SYNACK trasnmit/retransmit succeeds, for both IPv4 and IPv6.
