Description

5ghz is much cleaner spectrum than 2.4ghz, so defaulting to ht40+ makes sense.

This will be fixed in the first rc7 smoketest

Broken on the latest rc7 smoketest:
root@OpenWrt:~# wifi up
[...]
Configuration file: /var/run/hostapd-phy1.conf
HT40 channel pair (40, 1) not allowed
Interface initialization failed
[...]

Cerofiles' mac80211.sh needs to use channel 36 or 44 when using HT40+ per the freq table at http://hostap.epitest.fi/gitweb/gitweb.cgi?p=hostap.git;a=blob;f=hostapd/hostapd.conf;hb=HEAD#l381.

OpenWrt's mac80211.sh is currently using channel 36.

I will use 36 in rc7-smoketest4 (this is still broken in smoketest3). Thx for the heads up. I would prefer frankly to not use 36 or 44, but something higher, as to not conflict with other APs by default.

The much higher 149 or 157 are available.

http://huchra.bufferbloat.net/~cero1/rc7-smoketests/rc7-smoketest4/

has HT40+ enabled on channel 36. It's also from openwrt head.
