In case some CPUs don't support AVX512. Enable AVX2 for them to get better per-core performance.
In the single queue model, the same descriptor queue is used by SW to post descriptors to the device and used by device to report completed descriptors to SW. While as the split queue model separates them into different queues for parallel processing and improved performance. v10: *Changed desc reading style in Rx path. v9: *Some minor fixes. v8: *Reworked the receive func to avoid race conditions in Rx path. *Removed unnecessary compiler barriers. v7: *Removed (char) casts, ifdef block as suggested. *Fixed indentation, line wrapping. *Did blind write of data to avoid branching. *changed desc building and writing order for Tx. v6: *used single load/store in splitq_recv_pkts function. *removed x86-specific intrinsics from common code. v5: *Fixed CI errors. *Used defined constants instead of numbers. v4: *moved splitq_rearm_common to a common location. *reduced duplication of code. *fixed splitq_recv_pkts function. v3: *Fixed some indentation issues. *Collapsed wrapper and core function into one. *Fixed some pointer casting and naming inconsistency issues. v2: *Fixed CI build related issues. *Rebased on top of idpf/cpfl rx path selection simplication patch.
