Re: [PATCH iproute2-next 1/3] Add, show, link, remove IOAM namespaces and schemas

+		sprintf(data, "0x%" PRIx32,
+			(uint32_t)rta_getattr_u32(attrs[IOAM6_ATTR_NS_DATA]));
+
+		print_string(PRINT_ANY, "data", ", data %s", data)

The json_print has ability to handle hex already
Why not
print_hex(PRINT_ANY, "data", ", data %#x",
		rta_getattr_u32(...

Hmmm, sorry for that, you're right. I already had this code ready for a long time and forgot to use print_hex instead (as I did for patch #2).
