Before introducing libeth_xdp, we need to add a couple more generic helpers. Notably: * 01: add generic loop unrolling hint helpers; * 04: add helper to get both xdp_desc's DMA address and metadata pointer in one go, saving several cycles and hotpath object code size in drivers (especially when unrolling). Bonus: * 02, 03: convert two drivers which were using custom macros to generic unrolled_count() (trivial, no object code changes).
