Hi,

I think this is a good time to remove the deprecated netlink interface
for 802.15.4.

Stefan please say your opinion here. There should be really nobody which
use this interface anymore.

My mind haven't really changed on this topic. I understand why you want it removed but given that the general rule of the kernel is to have backward compatibility we can't just remove it. Dropping the old netlink interface breaks userspace compatibility, even if it only is for deprecated tools like lowpan-tools, etc.

My take on it is that we live with it. Keeping it around but not extending it. Maybe add a warning to dmesg iwhen some application uses the old interface.

Is it more code cleanliness/maintenance or bug reports that urge you to get rid of it?

regards
Stefan Schmidt
