Causing build error for arm, it looks like related to rte_memcpy macro:

.../lib/librte_ethdev/rte_flow.c: In function ‘rte_flow_conv_item_spec’:
.../lib/librte_ethdev/rte_flow.c:373:58: error: macro "rte_memcpy" passed 9
arguments, but takes just 3
       (size > sizeof(*dst.raw) ? sizeof(*dst.raw) : size));
