Bruno Randolf 40ca22eafe ath5k: add sysfs files for ANI parameters
/sys/class/ieee80211/phy0/device/ani/ani_mode
/sys/class/ieee80211/phy0/device/ani/noise_immunity_level
/sys/class/ieee80211/phy0/device/ani/spur_level
/sys/class/ieee80211/phy0/device/ani/firstep_level
/sys/class/ieee80211/phy0/device/ani/ofdm_weak_signal_detection
/sys/class/ieee80211/phy0/device/ani/cck_weak_signal_detection
/sys/class/ieee80211/phy0/device/ani/noise_immunity_level_max
/sys/class/ieee80211/phy0/device/ani/spur_level_max
/sys/class/ieee80211/phy0/device/ani/firstep_level_max

sysfs has a lot of symlinks, so you can find the files also in other locations,
like (by PCI ID) /sys/devices/pci0000:00/0000:00:11.0/ani and others.
