Before this patch, num_retrans = 0 for the first SYN/ACK and the first retransmitted SYN/ACK; however, an upcoming change will need to differentiate between those two conditions.
AFAICS, send_synack is invoked with a NULL dst only on retransmissions. Perhaps you could use that info instead? moving forward and backward a counter is not so nice.
