[ih] bufferbloat and modern congestion control (was 4004)

Sorry about the two messages.  I just thought I was in the black hole again and decided might as well do some minor editing

  Yes there are more ICMP messages. Redirect popped into my head after my initial message about the Reconstitution Protocol gateway and Source Quench. It was like oops maybe remembered wrong. I haven't had a chance to check out the RP document yet. :-(
Doesn't ping use icmp request and reply? In the past I wondered if a dislike for ping started this we should just drop ICMP messages.
