[Bloat] *under*bloated networks

[Dave Taht]

In the last two weeks I have found two dramatically underbuffered Gbit
fiber networks.

This one appears to have about a 400 full size packet uplink buffer (5ms)[1]

It was pretty remarkable to see how well multiple tcp flows still
achieved close to the full rate with such a small fixed size queue,
eventually.

A single bbr flow can't crack 150mbits: https://imgur.com/a/DpydL5K.

offload, which is, seemingly good to a gbit at least on one direction.
