[PATCH v2 00/15] net/intel: rx path selection simplification

[Ciara Loftus <ciara.loftus@intel.com>]

This series aims to simplify the process of selecting an Rx burst
function for the i40e, iavf and ice drivers. Three main simplifications
are made:
1. enforcing the same rx burst function for both primary and secondary
processes.
2. using a common function for determining the maximum SIMD width based
on compiler flags, CPU flags and user-defined limits.
3. using a common function for selecting the rx burst function based on
maximum SIMD width, function features (flex desc, scattered, bulk alloc)
and requested rx offloads.

v2:
* use booleans instead of a mask to represent path features
* updated ci_rx_path_select() to improve readability
* removed check for RTE_CPUFLAG_AVX512F in AVX2 support check
* reordered enum i40e_rx_func_type and i40e_rx_path_infos array
* renamed "burst" to "path" in various places
* reordered iavf_rx_func_type and iavf_rx_path_infos array
* reordered ice_rx_func_type and ice_rx_path_infos array
* fixed secondary process path selection for ice
