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 Signed-off-by: Li Zhang --- doc/guides/rel_notes/release_21_05.rst | 7 ++ lib/librte_ethdev/rte_mtr.h | 89 ++++++++++++++++++++++---- 2 files changed, 85 insertions(+), 11 deletions(-) diff --git a/doc/guides/rel_notes/release_21_05.rst b/doc/guides/rel_notes/release_21_05.rst index 3c76148b11..c9c15794ad 100644 --- a/doc/guides/rel_notes/release_21_05.rst +++ b/doc/guides/rel_notes/release_21_05.rst @@ -119,6 +119,13 @@ New Features * Added command to display Rx queue used descriptor count. ``show port (port_id) rxq (queue_id) desc used count`` +* **Added support for meter PPS profile.** + + Currently meter algorithms only supports bytes per second(BPS). + Add packet_mode in the meter profile parameters data structures + to support packet per second (PPS) mode. + So that it can meter traffic by packet per second. + Packet_mode must be 0 when it is bytes mode.
