Subject: [dpdk-dev] [PATCH v2 1/4] ethdev: add packet mode in meter profile structure
Date: Thu,  8 Apr 2021 06:58:45 +0300
Message-ID: <20210408035849.1755493-2-lizh@nvidia.com> (raw)
In-Reply-To: <20210408035849.1755493-1-lizh@nvidia.com>

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.

The below structure will be extended:
rte_mtr_meter_profile
rte_mtr_capabilities
