[dpdk-dev] [PATCH v3 0/4] Support PPS(packet per second) on meter

[Li Zhang]

Currently meter algorithms only supports rate is bytes per second(BPS).
Add packet_mode flag in meter profile parameters data structure.
So that it can meter traffic by packet per second.

When packet_mode is 0, the profile rates and bucket sizes are
specified in bytes per second and bytes
when packet_mode is not 0, the profile rates and bucket sizes are
specified in packets and packets per second.

Add the necessary checks to the existing drivers implementing
the rte_mtr API to makes sure that profiles with
packet_mode set to TRUE are rejected.

Depends-on: series=15998  ("Add ASO meter support in MLX5 PMD")
https://patchwork.dpdk.org/project/dpdk/list/?series=15998

V2: create a unified patch that contains both the series with
	the API changes and the series with the necessary error checks in the drivers.

V3: Fix comments from Matan and Cristian.
