Hi!
I'm trying to use HT40 channels on a Rt3050 SoC. I already fixed some stuff in
the rt2x00 driver to set the RF in the exact same way as the rt2860v2 driver
does. However, hostapd somehow still doesn't setup HT40 properly, though the
debug output of hostapd says:
HT40: control channel: 11  secondary channel: 7
Completing interface initialization
Mode: IEEE 802.11g  Channel: 11  Frequency: 2462 MHz
nl80211: Set freq 2462 (ht_enabled=1 sec_channel_offset=-1)

Still HT40- is not configured properly:
root@OpenWrt:/sys/kernel/debug/ieee80211/phy0# cat channel_type
no ht

TCP transfer rates are then much lower than in HT20 mode (around 600kbit/s
instead of somewhere around 25MBit/s), supposingly because hostapd announces
HT40- capability but doesn't operate the WiFi hardware in that mode.
When I -- just after starting hostapd -- manually set the channel to HT40- by
root@OpenWrt:/sys/kernel/debug/ieee80211/phy0# iw phy phy0 set channel 11 HT40-
root@OpenWrt:/sys/kernel/debug/ieee80211/phy0# cat channel_type
ht40-

This kinda fixes it a bit and I can at least reach the same bandwidth as in
HT20, but that seems to be related to the way the rt2x00 tells mac80211 about
the supported transfer rate (should just be doubled, from what i read in the
code, but haven't fully figured it out yet).

Any ideas?

Cheers

Daniel
