[RFC net-next 0/2] net: sched: add Flow Queue PIE AQM

[Gautam Ramakrishnan <gautamramk@gmail.com>]

Flow Queue PIE packet scheduler

This patch series implements the Flow Queue Proportional
Integral Controller (FQ-PIE) active queue management
algorithm. It is an enhancement over the PIE algorithm.
It integrates the PIE aqm with a deficit round robin
scheme.

It is implemented over RFC 8033 aligned version of PIE.
In this patch, Little's law is used for queue delay
estimation like PIE. This patch doesn't yet have the
timestamp based queue delay estimator like freebsd, that
Dave Taht thinks is better.

We are looking for suggestions on cleanups and
improvements for this patch.
