+Subject: iproute2: devlink: port from sys/queue.h to list.h
+
+sys/queue.h does not exist on linux-musl targets and fails build as:
+
+    devlink.c:28:10: fatal error: sys/queue.h: No such file or directory
+       28 | #include <sys/queue.h>
+          |          ^~~~~~~~~~~~~
+
+The change ports to list.h API and drops dependency of 'sys/queue.h'.
+The API maps one-to-one.
+
+Build-tested on linux-musl and linux-glibc.
