Try my 4 patches in kernel:
[RFCv3 1/4] mac80211: ibss/mesh move bw checking
[RFCv3 2/4] cfg80211: add VHT support for IBSS
[RFCv3 3/4] mac80211: IBSS fix scan reques
[RFCv3 4/4] mac80211: add VHT support for IBSS

And hostap:
[PATCH 1/2] ibss: fix control freq if IBSS already found
[PATCH 2/2] ibss: add fixed freq ssid param
[RFC 1/2] hostap: make hostapd_set_freq_params() common
[RFC 2/2] ibss: add support for VHT80 configuration

+ set NL80211_FEATURE_IBSS_VHT flag in ath10k driver
+ wpa_s->drv_flags |= WPA_DRIVER_FLAGS_VHT_IBSS in wpa_supplicant
(this will be set base on NL80211_FEATURE soon)

I have about ~250Mbps UDP between two ath10k 2x2.
