This RFC intends to provide a way to dump all the offloaded rte flows
in HW. This is very helpful for user and developer to debug flow offloading
stuff, i.e, to check whether PMD offloads the rte flow in a correct way
from HW perspective.

A private PMD API is provided as well as a socket server for external tool
to trigger dump.
The output file is in raw format and Mellanox specific. An external vendor
(Mellanox) provided tool is needed in order to get human readable format.

Please be aware the underlying rdma-core lib also needs to support this.

  net/mlx5: support flow dump Api
  app/testpmd: new flow dump CLI
  net/mlx5: add socket server for external tools
  doc: update mlx5 document for flow dump feature
