> v19 Changes:
> - Fixed vector Rx burst function being overwritten by scalar selection.
> - Refactored Rx/Tx mode set functions to seed flags from caps first,
>   eliminating tautological checks.
> - Added memset for mbuf_def in vector init to avoid uninitialized reads.
> - Converted pci_map_addr_info to designated initializers.
> - Removed dead Windows-only code in meson.build.
> - Added NULL checks for mbuf free for driver-wide consistency.
> - Updated burst_mode_get to accurately report AVX paths.
> - Adjusted SXE2_ETH_OVERHEAD to match actual VLAN capabilities.
