I am running openSUSE Leap 42.2/42.1 on (three) different laptops using
kernel-default from the "Kernel:stable" repository.

Since update to Kernel 4.10.0 a few days ago, setting regulatory domain via iw
reg set or through udev/crda fails.

On 42.2 system logs are filled with

systemd-udevd[20429]: Process '/usr/sbin/crda' failed with exit code 251.

every few seconds. (I assume the only reason I don't see this on 42.1 is the
older version of systemd.)

Some additional information:

- First, I tried Kernel 4.9.11 (the last 4.9.x in Kernel:stable) and the
problem is not present there

_ Trying to run crda manually (yes, I know this has to fail) gives some
interesting additional information.

On Kernels < 4.10.0:

crda
COUNTRY environment variable not set.

COUNTRY=DE crda ; echo $?
Failed to set regulatory domain: -7
249

On Kernel 4.10.0:

COUNTRY=DE crda ; echo $?
nl80211 not found.
251

So here is our error code 251 again.
