Hello,
I have successfully installed the latest version of ath10k driver from
backports.
However, I have some difficulties on configuring wpa_supplicant for IBSS
VHT mode.
Looked at wpa_supplicant configuration file, but I couldn't found any
option
related to explicit setting VHT (though I've found disable_vht instead)
Sorry for annoying questions, but can you help this out?
At least you could let me know your configuration of wpa_supplicant.
Thanks much,

Hello,
Thanks much for your help.
However, I have looked at my driver code and
did not find any implementations such as wiphy_ext_feature_set()
or NL80211_EXT_FEATURE_VHT_IBSS.
It seems not simple to apply your patch into my version of ath10k
device
driver.
I am currently using backports-3.16-rc1-1 for ath10k device driver
code
in order to match the kernel version v3.16 for Ubuntu 14.04.02.
You can use newest backports with older kernel (new
mac80211/cfg80211/drivers with old kernel).
Or you can build and install new kernel for Ubuntu.
I am using https://github.com/kvalo/ath

Could you tell me the version of kernel and ath10k device driver of
your
test configuration?
Or is there any way to apply your version of patch code into linux
kernel
v3.16?
(I expect the version will be much more recent one than mine)
Thanks,

Enable VHT support for IBSS, while mac80211/cfg80211 and
wpa_supplicant already support this.
In my test env, ath10k 2x2 I get:
(udp) ath10k-1 >>>> ath10k-2 (server) - speed: 419 Mbits/sec
(tcp) ath10k-1 >>>> ath10k-2 (server) - speed: 404 Mbits/sec
During tests I used wpa_supplicant (current version), which
already support IBSS VHT, and choose highest available BW.
