Use an algorithm similar to that in tcp_notify() to determine if
...
syn_cache_unreach() should remove the entry, or just continue on.
Algorithm is to only remove the entry if we've had more than one unreach
error and have retransmitted 3 or more times. This prevents the following
scenario, as noted in PR #5909 (PR from Ty Sarna, scenario from
Charles Hannum):
* Host A sends a SYN.
* Host A retransmits the SYN.
* Host B gets the first SYN and sends a SYN-ACK.
* Host B gets the second SYN and sends a SYN-ACK.
* One of the SYN-ACK bounces with an
ICMP unreachable, causing the `SYN cache' entry to be
removed with no notification.
* Host A receives the other SYN-ACK, sends an ACK, and goes to
ESTABLISHED state.
Should fix PR #5909 .

Put original hash function back. It wastes a little bit of space, but is much more even -- think of the case of a web service provider, some of whose customers end up getting 'inferior service' because they're on addresses that happen to be out at the end of a hash chain. With webservers with thousands of addresses, this is a real issue. If the wasted space is a big deal, we could pick a prime number that's slightly _less_ than a power of two...
