Hi Daniele
This range can be from 1-254.
+
+static void explain(void)
+{
+ print_explain(stderr);
+}
+
+static int rmnet_parse_opt(struct link_util *lu, int argc, char
**argv,
+ struct nlmsghdr *n)
+{
+ __u16 mux_id;
+
+ while (argc > 0) {
+ if (matches(*argv, "mux_id") == 0) {
+ NEXT_ARG();
+ if (get_u16(&mux_id, *argv, 0))
+ invarg("mux_id is invalid", *argv);
+ addattr_l(n, 1024, IFLA_RMNET_MUX_ID, &mux_id, 2);
You could use addattr16() instead since it is __u16.
