It looks like size is not constant in the above instances.
Try writing an intermediate wrapper using __rte_constant() to verify at build
time.
Something like (assuming the return value is unused):
#define rte_memcpy_const_size(dst, src, n) \
do { \
RTE_BUILD_BUG_ON(!__rte_constant(n)); \
memcpy(dst, src, n); \
} while (0)
