I'm currently working on a design with ls1043a SoC that has a DPAA block. Looking in to DPAAs capabilities there is a feature in it called offline ports. I'm trying to read the current documentation but can not see the real use case for the offline ports. Can anyone give me some background and additional context here? Give me use case(s) for the offline ports in DPAA.
As far as I understand the documentation the offline ports in DPAA is a way for software to directly access FQs in QMAN. It is a way for software to send frames in to the queues that then take the normal route through FMAN with possibility to PCD and after that ends up in a new FQ. Got it correct?
