Fix the NEXT_IA_WITH_SAME_ADDR macro introduced in 1.27: it was finding
...
the first in_ifaddr structure with a different internet address! Reverse
the sense of the test. Spotted by and fix from Eric Haszlakiewicz.

change IN_IFADDR_HASH_SIZE to 509, which actually uses no more space than 293 due to rounding up to nearest power of two in hashinit.

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...

The rewrite of if_arp.c to work with the hashed interface address lists
...
(1.44) missed a test for the right interface, making some machines answer
to some bogus arp requests (like for WHO-HAS 127.0.0.1).
The quick patch in 1.46-1.47 does not work for so-called "unnumbered"
interfaces, that is, (point-to-point) interfaces that share their local
address with another (e.g., the Ethernet) interface.
We add a macro to in_var.h, to step (in the current implementation) through
the hash chain and fine more entries with the same address, and use that
in if_arp.c to find one which belongs to our interface.

Eek, we were wasting almost half of the in_ifaddr hash space by modulo'ing
...
with IN_IFADDR_HASH_SIZE. Instead, AND with the hash mask computed by
hashinit().

Default IP flow to being enabled. Add a sysctl to control the maximum

number of flows (net.inet.ip.maxflows). If set to 0, will disable fast
path forwarding.

Add support for "fast" forwarding. Add hooks in if_ethersubr.c and
...
if_fddisubr.c to fastpath IP forwarding. If ip_forward successfully
forwards a packet, it will create a cache (ipflow) entry. ether_input
and fddi_input will first call ipflow_fastforward with the received
packet and if the packet passes enough tests, it will be forwarded (the
ttl is decremented and the cksum is adjusted incrementally).
