This  "!raw_mask->pattern " is useless here, because there is check for this parameter
In the code behind, so I will delete it in v4.

	for (index = 0; index < raw_spec->length; index++) {
		if (raw_mask->pattern[index] != 0xFF) {
			memset(filter, 0, sizeof(struct rte_eth_flex_filter));
			rte_flow_error_set(error, EINVAL,
					RTE_FLOW_ERROR_TYPE_ITEM,
					item, "Not supported by flex filter");
			return -rte_errno;
		}
	}
