Rocev2PortConfig Writable Attributes

Attribute Description
Common Writable Attributes Active, Name
AdditiveIncreaseRateInMbps

NOTE: This attribute is deprecated. It will be removed in subsequent releases, so it is recommended that you do not use it.

Indicates the Mbps rate increase step to raise the target rate in each stage of the additive increase phase.

Type: double

Default: 5.0

Range: 1 - 100000
AiSteps

Indicates the max number of the additive increase steps to increase the rate to the maximum rate for the queue pair.

Type: u8

Default: 8

Range: 1 - 8
AiTimerInMs

Indicates the additive increase timer in milliseconds for the queue pair.

Type: double

Default: 0.055

Range: 0 - 21990
Alpha

Determines the aggressiveness of the initial rate drop for the queue pair.

Type: double

Default: 1.0

Range: 0.001 - 1.999
AlphaUpdatePeriodInMs

NOTE: This attribute is deprecated. It will be removed in subsequent releases, so it is recommended that you do not use it.
