Fine if you don't mind an indirect function call pointer somewhere in the TCP
hash path.
I'm thinking about adding one that removes the separate time wait
table. It is not needed for desktops because they should have little
or no time-wait sockets. also it should throttle the hash table
sizing aggressively; e.g. 256-512 buckets should be more than enough
for a client.
BTW I noticed that 1/4 of the big hash table is not used on SMP. The
time wait buckets share the locks of the lower half, so the spinlocks
in the upper half are never used. What would you think about splitting
the table and not putting spinlocks in the time-wait range?
