dpdk: fix prefetch assert on Arm
CLIB_PREFETCH (cop[1], CLIB_CACHE_LINE_BYTES * 3, STORE);
Note on 64 bytes cache line size arm machines,
CLIB_CACHE_LINE_BYTES 128
CLIB_CACHE_PREFETCH_BYTES 6
above CLIB_PREFETCH () macro will be expand to
ASSERT ((size) <= 4 * CLIB_CACHE_PREFETCH_BYTES);
it will hit assert due to size (i.e. 3 * 128) > 4 * 64
Solution:
Change to CLIB_PREFETCH (cop[1], sizeof(*cop[1]), STORE);
Type: fix
