Well, it is one line only starting on line 204 of 
/usr/lib/lua/luci/model/cbi/admin_network/wifi.lua
I patched it one of my routers, which is probably a bit (r44004) out of 
sync with the trunk:

  htmode = s:taboption("advanced", ListValue, "htmode", translate(
...
*htmode:value("NOHT", translate("Greenfield mode: off"))*

I'll try to "git" it as described.

Ok, I can live with that explanation. :)

Sure, thanks! Brace for test tickets ;)
BTW: How to apply for an account there?

Ok, that will do fine, I think.

I came across some other issues, which I am not sure where to address 
them to:

1. rsn_preauth - netifd: an unset variable "$bridge instead of 
$network_bridge is being checked - resulting in auth_cache being 0 always.
Changing that will activate rsn_preauth on all interfaces, ... even 
those not configured for radius. I am looking for a more detailed 
documentation of netifd.

2. Transmit power settings (more OpenWRT basics, than LuCI's):
a) Ath9k ought to be accepting negative values until -5dB(m) (according 
to a post by Adrian Chadd in 2011; with some "unless ..."). I don't seem 
to be able to set values below 100mB(m) with iw, which netifd relies on. 
Is this to be forwarded to linux wireless or is this a known issue with 
ath9k on certain devices? (Trying this on e.g. a NanoStation M5 Loco).

b) iwinfo wlan0 txpowerlist shows no negative values neither on TP-LINK 
TL-WR1043ND v1 and v2, nor on Ubnt NSM5L. Where does iwinfo, which feeds 
this info to netifd, if a read the source correctly, get these values 
from - firmware or driver?

c) I seem to be unable to set values below 5dB or 3dB respectively, 
effectively on those devices. Are there some offsets and why?

3. In order to get the amount of "Available Antennas", what would be the 
most appropriate and reliable way?
     a) iw list  | grep "Available Antennas:"
     b) grep "X Mask" /sys/kernel/debug/ieee80211/phy0/ath9k/base_eeprom 
(compiled without debugfs: certainly fails)
     c) ?

I guess you can help, since you are certainly more familiar with the 
code, than me.
Thanks in advance!

Thank you, same to you!
