From: Luis R. Rodriguez <lrodriguez at qualcomm.com>

Here's a v4 which corrects one bug (rather typo) and one uneeded
blank line hunk. This also rebases on top of today's hostapd.git.
This also casts to (unsigned long int) the u64 on debug prints
for the survey as in some compilers it will rant.

For more details please refer to:

You can get the v4 single patch file from:

http://www.kernel.org/pub/linux/kernel/people/mcgrof/patches/hostapd/acs-all-in-one-v4.patch

When you run this you should get sometime like:

mcgrof at mouche ~/hostap/hostapd (git::master)$ sudo ./hostapd /home/mcgrof/wpa/hostapd.conf 
Configuration file: /home/mcgrof/wpa/hostapd.conf
ACS: automatic channel selection started, this may take a bit
ACS: Ideal chan: 9 (2452 MHz) Average interference factor: -3.403722
Using interface wlan0 with hwaddr 00:03:7f:11:a3:f3 and ssid 'pogo'

mcgrof at mouche ~/hostap/hostapd (git::master)$ grep acs /home/mcgrof/wpa/hostapd.conf 
channel=acs_survey
acs_num_req_surveys=5
acs_roc_duration_ms=5

Luis R. Rodriguez (4):
  hostapd: split up channel checking into helpers
  hostapd: add offchannel support
  hostapd: add survey dump support
  hostapd: add Automatic Channel Selection (ACS) support
