Dear all,
I am working with transceiver AT86RF233 on a board with Variscite i.MX 6 SOM.
I'm using IEEE802154 sockets in the following test code:
#include<errno.h>
#include <stdio.h>
#include <sys/ioctl.h>
#include <string.h>
#include <net/if.h>
int main () {
int socketfd = 0;
struct ifreq ifr;
static const char *wpandevs[] = {"wpan0"};
int ret;
socketfd = socket(PF_IEEE802154, SOCK_RAW, 0);
strncpy(ifr.ifr_name, wpandevs[0], IF_NAMESIZE);
printf("d0\n");
ret = ioctl(socketfd, SIOCGIFADDR, &ifr);
printf("d1\n");
if (ret < 0) {
fprintf(stderr,"ioctl: SIOCGIFADDR error\n");
return;
}
printf("d2\n");
return 0;
}
But when I execute this code, kernel says to me following error messages:
RTNL: assertion failed at net/mac802154/iface.c (65)

Do you have some tips to solve the problem?
I'm using Debian Jessie (downloaded here
http://www.variwiki.com/index.php?title=VAR-SOM-MX6_Debian_R2) with
kernel 4.1.15-224528-gc28c3ac-dirty.
Best,
Luca Di Mauro
