Ath 40MHz on 2.4GHz?

[Sven Hazejager]

Does ath on CURRENT support 40Mhz channels on 2.4GHz for 802.11n? If
yes, how do I enable it?

I now have in rc.conf:

wlans_ath0="wlan0"
create_args_wlan0="wlanmode hostap"
ifconfig_wlan0="inet 192.168.2.1 netmask 255.255.255.0 country NL mode
11ng channel 6:ht/40-"

ifconfig -v wlan0 shows (amongst other things):

        status: running
        ssid KL5 channel 6 (2437 MHz 11g ht/40+) bssid 00:0b:6b:b1:3a:e7

I would like to use channel 1 as the secondary channel...

Thanks
Sven
