+Subject: netlink: settings: Fix lanes parameter format specifier
+
+Lanes parameter is not printed well on ethtool base command causing the
+following output:
+
+$ ethtool swp1
+
+[..]
+        Speed: 400000Mb/s
+Segmentation fault (core dumped)
+
+Use the "%u" format specifier instead of "%s", since the lanes parameter
+type is unsigned integer and not a string.
+
+Fixes: bd1341cd2146 ("add json support for base command")
