Hi,
On BSD, specifically FreeBSD, when disabling the RF radio on a laptop with
communication device toggle key (as it's called on my laptop) otherwise
known as the RF radio kill button, the following errors will be issued once
per second:
May 19 17:58:35 slippy wpa_supplicant[391]: wlan0: CTRL-EVENT-SCAN-FAILED
ret=-1 retry=1
May 19 17:58:36 slippy wpa_supplicant[391]: ioctl[SIOCS80211, op=103,
val=0, arg_len=128]: Device not configured
On Intel the device will remain up however the IFF_RUNNING flag indicates
whether the device is actually enabled and active. The following patch
tests for this and avoids spamming syslog when RF is disabled.
Silence the once per second CTRL-EVENT-SCAN-FAILED errors when the WiFi
radio is disabled through the communication device toggle key (also known
as the RF raidio kill button). Only the CTRL-EVENT-DISCONNECTED will be
issued.

Thoughts?
