DPDK sched library is equipped with mechanism that secures it from the bufferbloat problem
which is a situation when excess buffers in the network cause high latency and latency
variation. Currently, it supports RED for active queue management. However, more
advanced queue management is required to address this problem and provide desirable
quality of service to users.
This solution (RFC) proposes usage of new algorithm called "PIE" (Proportional Integral
controller Enhanced) that can effectively and directly control queuing latency to address
the bufferbloat problem.
The implementation of mentioned functionality includes modification of existing and
adding a new set of data structures to the library, adding PIE related APIs.
This affects structures in public API/ABI. That is why deprecation notice is going
to be prepared and sent.
