QCA9984 ap mode with ath10k backport cannot be connect

Thu Nov 9 21:39:49 PST 2017

your hostapd config does not contain the bridge. beside this i wont see 
much details about your network  configuration.
the hostapd log shows the the client is leaving by itself. (local 
reason).  so the ap is working.
so check if your dhcp server is configured properly and fix yôur hostapd 
config to handle the bridged interface

bridge=wifibr0 is missing

your vht flags are wrong too.

vht_capab=[RXLDPC][SHORT-GI-80][SHORT-GI-160][TX-STBC-2BY1][RX-STBC-1][SU-BEAMFORMER][MU-BEAMFORMER][SU-BEAMFORMEE][RX-ANTENNA-PATTERN][TX-ANTENNA-PATTERN][MAX-MPDU-11454][VHT160-80PLUS80][MAX-A-MPDU-LEN-EXP7][BF-ANTENNA-2][SOUNDING-DIMENSION-2][BF-ANTENNA-3][SOUNDING-DIMENSION-3] 

would be correct for 9984 with full features (taken from my config)

so BF-ANTENNA-4 and SOUNDING-DIMENSION-4 is wrong

i have 9984 working without issues
