> Received packets can be aligned to the size of the cache line on

> This feature is supposed to be controlled by the rxq_pkt_pad_en
> devarg and it is true for an RxQ created via the Verbs API.
> But in the DevX API case, it is erroneously controlled by the
> rxq_cqe_pad_en devarg instead, which is in charge of the CQE
> padding instead and should not control the RxQ creation.
> Fix DevX RxQ creation by using the proper configuration flag for
> Rx packet padding that is being set by the rxq_pkt_pad_en devarg.
