CT ath10k firmware now supports IBSS + RSN

[Ben Greear <greearb@candelatech.com>]

First, thanks to everyone that helped me with questions,
QCA/Tieto's upstream patches, etc.

This needs more testing, but it appears to at least mostly work.

I am using this 4.0 related kernel.  I think only the last 3 patches
are IBSS specific, but possibly there are others that matter as well.

Firmware binaries and release notes are here:

I'm using a very recent wpa_supplicant..upstream should work I think,
but I am using this one:

https://github.com/greearb/hostap-ct/tree/master/hostapd

supplicant needs to have this enabled, among other things:

CONFIG_IBSS_RSN=y


I suspect there are lingering bugs, perhaps in supplicant, as it seems to take
a few tries for the 4-way to happen properly, and I have to re-start hostapd
on each side each time I associate.

My supplicant config files look like this (you can comment out any options
your supplicant doesn't know about...I have a few extra features not specifically
related to IBSS in my hostapd tree)

ctrl_interface=/var/run/wpa_supplicant
fast_reauth=1
concurrent_assoc_ok=1
scan_cur_freq=1
min_scan_gap=5
freq_list=5180

bss_max_count=2000
network={
    ssid="ota-ibss-ssid"
    disable_ht=0
    disable_vht=0
    ieee80211w=0
    disable_ht40=1
    disable_sgi=0
    ht_mcs=""
    disable_max_amsdu=-1
    ampdu_factor=-1
    ampdu_density=-1
    freq_list=5180
    fixed_freq=1

    mode=1
    frequency=5180
    proto=RSN
    key_mgmt=WPA-PSK
    #psk="ben-ota-passwd"
    psk=fc29b6edf32abd7a9818af3c94b2aa5364c785eee33ed3df11605a3db8f905bc
    pairwise=CCMP
    group=CCMP
    proactive_key_caching=0

}


I'm curious to know if anyone tries it out.

Thanks,
Ben
