That TOE/iWARP could end-up being precluded by NAT seems so ironic
from a POE2E standpoint.

To be honest we do not have a pure end to end internet, and some of
our failed experiments in the past prove this :-)

For example, we have an optimization that allows much earlier
termination of TIME_WAIT connections.  It relies upon TCP timestamps
and attributes we can determine about end hosts using that information
(it is yet another Van Jacobson idea btw).  But NAT means that IP+Port
does not necessarily equate to the same host over time, not even over
short periods of time.  A NAT box could be using Port X for host A and
then host B some short time later.

Therefore we had to disable the early timewait recycling trick by
default.
