[RFE] Add DSCP mark 44

[Rodolfo Alonso]

This RFE proposes to add a new valid DSCP mark value: 44.

This value was recently added in the RFC5865 [1]: "A Differentiated Services Code Point (DSCP) for Capacity-Admitted Traffic".

Fix proposed to branch: master

I don't think that we really need to discuss it as an RFE

[Lajos Katona (lajos-katona)]

Just to be sure we discussed this during the drivers meeting (see [1]), and agreed that this is an obvious extension of current DSCP QoS code, and we don't need a new API extension as QoS rule types API is available to fetch the available DSCP codes for example (see [2]). Note: The api-ref should be updated to have suche example in it.

    Retrieve the DSCP valid marks from the API

    Instead of relying on a constant, read the DSCP valid supported marks
    from the API, using the 'qos-rule-type-details' call [1].
