Ieee802154 socket problem with SIOCGIFADDR

[Matteo Petracca <matteo.petracca@sssup.it>]

Dear all,
I am working on a BeagleboneBlack with transceiver at86rf233.

When using ieee802154 sockets in my code I have:

ret = ioctl(socketfd, SIOCGIFADDR, &ifr);

and everything works fine with kernel 3.8.13.

In kernel 4.0.1 the request fails with the following kernel messages:

[  846.038365] RTNL: assertion failed at net/mac802154/iface.c (65)

Do you have any idea how to solve the problem?

Best,
