wlan_scan_ap and wlan_scan_sta

[Janos Dohanics]

According to the Handbook, I can compile into the kernel

device wlan_scan_ap      # 802.11 AP mode scanning
device wlan_scan_sta     # 802.11 STA mode scanning

But when I do, I get:

config: Error: device "wlan_scan_ap" is unknown
config: Error: device "wlan_scan_sta" is unknown
config: 2 errors
*** Error code 1
1 error
*** Error code 2
1 error

I'm wondering why? 6.4-PRERELEASE, amd64
