> v5:
> - Set rxdid = 0 in iavf_configure_queues() when it's supported and
> RTE_LIBRTE_IAVF_16BYTE_RX_DESC is y. So the error can be captured
> explicitly as kernel PF does not support it yet.
> - Fix some build errors when RTE_LIBRTE_IAVF_16BYTE_RX_DESC is y.
>
> v4:
> - Avoid initial declaration in 'for' loop to backward-compatible
> with older gcc versions.
>
> v3:
> - Remove patch to query DDP package info as it's specific to DCF.
> - Specify fdir_ref_cnt as per VF value for enable/disable FDIR ID parse.
> - Move fdir_enabled flag to per Queue value for cache benefit when
> access in vector routines.
> - Store extracted flow_id value to mbuf without judgement to avoid
> branch speculation fail, which is benefit to performance.
>
> v2:
> - Revert macro RTE_LIBRTE_IAVF_16BYTE_RX_DESC deletion as
> it's defined in AVF spec.
> - Typo RTE_LIBRTE_ICE_16BYTE_RX_DESC fix in iavf_rxtx.c.
> - Move flex desc definitions into iavf_rxtx.h.
> - Up to date to match with the latest version of virtchnl.h.
> - Extract a new internal func iavf_update_rx_tail to call.
> - Remove
> iavf_dev_rxq_count_flex_rxd()/iavf_dev_rx_desc_status_flex_rxd(),
> as the accompanying legacy ones can deal with the flex desc cases.
> - Move rxq->rxdid assignment from iavf_configure_queues()
> to iavf_dev_rx_queue_setup().
> - Unfold _mm_extract_epi32(fdir_id0_3, i) to fix build error
> when using GCC compile option -O0.
