From: Luis R. Rodriguez <lrodriguez@xxxxxxxxxxxx> 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: http://wireless.kernel.org/en/users/Documentation/acs 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@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@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.
