Jiong Wang 8c90053858 nfp: bpf: implement memory bulk copy for length bigger than 32-bytes ... When the gathered copy length is bigger than 32-bytes and within 128-bytes (the maximum length a single CPP Pull/Push request can finish), the strategy of read/write are changeed into: * Read. - use direct reference mode when length is within 32-bytes. - use indirect mode when length is bigger than 32-bytes. * Write. - length <= 8-bytes use write8 (direct_ref). - length <= 32-byte and 4-bytes aligned use write32 (direct_ref). - length <= 32-bytes but not 4-bytes aligned use write8 (indirect_ref). - length > 32-bytes and 4-bytes aligned use write32 (indirect_ref). - length > 32-bytes and not 4-bytes aligned and <= 40-bytes use write32 (direct_ref) to finish the first 32-bytes. use write8 (direct_ref) to finish all remaining hanging part. - length > 32-bytes and not 4-bytes aligned use write32 (indirect_ref) to finish those 4-byte aligned parts. use write8 (direct_ref) to finish all remaining hanging part.
