This patch fixes the following error:
arpd.c:442:17: error: initialization of 'int' from 'void *' makes integer from pointer without a cast [-Wint-conversion]
442 | NULL, 0,
raised by Buildroot autobuilder [1].
In the case in question, the analysis of socket.h [2] containing the
msghdr structure shows that it has been modified with the addition of
padding fields, which cause the compilation error. The use of designated
initializers allows the issue to be fixed.
struct msghdr {
void *msg_name;
socklen_t msg_namelen;
struct iovec *msg_iov;
int __pad1;
int msg_iovlen;
int __pad1;
void *msg_control;
int __pad2;
socklen_t msg_controllen;
int __pad2;
int msg_flags;
};

Compatibility
-------------
A new release of iproute2 is done with each kernel version, but
there is a wide range of compatibility. Newer versions of iproute2
will still work with older kernels, but there are some limitations.
If an iproute2 command with a new feature is used with an older
kernel, the kernel may report an error or silently ignore the new
attribute. Likewise if older iproute2 is used with an newer kernel,
it is not possible to use or see new features. The range of
compatibility extends back as far as the oldest supported Long Term
Support (LTS) kernel version.
How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. include/uapi
This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
