iwlwifi: move debug_level to sysfs/bus/pci/devices
This patch ports the debug_level from sysfs/bus/pci/drivers/iwl4965 to /sys/class/net/wlanX/device/debug_level Signed-off-by: Ester Kummer <ester.kummer@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

control which debug output is sent to the kernel log by setting the
value in
- /sys/bus/pci/drivers/${DRIVER}/debug_level
+ /sys/class/net/wlan0/device/debug_level
This entry will only exist if this option is enabled.
To set a value, simply echo an 8-byte hex value to the same file:
- % echo 0x43fff > /sys/bus/pci/drivers/${DRIVER}/debug_level
+ % echo 0x43fff > /sys/class/net/wlan0/device/debug_level
