Field Documentation

enable

odp_bool_t odp_bp_param_t::enable

A boolean to enable Back pressure When true, back pressure is enabled and configured with the BP parameters.

Otherwise BP parameters are ignored. Default value is false.

Definition at line 395 of file api/spec/classification.h.

threshold

odp_threshold_t odp_bp_param_t::threshold

Threshold value for back pressure.

BP is enabled when the resource usage is equal to or greater than the max backpressure threshold. Min threshold parameters are ignored for BP configuration.

See also

odp_red_param_t for 'resource usage' documentation.

Definition at line 403 of file api/spec/classification.h.

pfc_level

uint8_t odp_bp_param_t::pfc_level

PFC priority level.

When enabled (ODP_PKTIO_LINK_PFC_ON), PFC frames are generated when the above threshold is exceeded. The generated frames request the receiver to temporary halt transmission of traffic on this priority level (0 .. 7).
