This patch fixed the following build error on openSUSE Leap 15.3:
=======================================================================
gcc nf-queue.c -lmnl -o tools/testing/selftests/netfilter/nf-queue
nf-queue.c:13:10: fatal error: libmnl/libmnl.h: No such file or directory
#include <libmnl/libmnl.h>
^~~~~~~~~~~~~~~~~
compilation terminated.
=======================================================================
It is because libmnl.h is put in the directory of
"/usr/include/libmnl/libmnl/" on openSUSE, not "/usr/include/libmnl/":
> rpm -ql libmnl-devel
/usr/include/libmnl
/usr/include/libmnl/libmnl
/usr/include/libmnl/libmnl/libmnl.h
/usr/lib64/libmnl.so
/usr/lib64/pkgconfig/libmnl.pc
