I printed these 2 parameters and saw that data_tx_status=0, it depends on >>NL80211_FEATURE_SK_TX_STATUS and this parameter was affected to the flags of wiphy->features, defined in /net/mac80211/main.c.I find this parameter was set = 0 in /backport-include/linux/nl80211.h

Your firmware allows me  to enter the promiscuous mode to set up bridge network for myStation (using wpa_supplicant), If I use the official firmware (10.1.467-2.1) for my station, it crashed after associated with an AP. Thing that I've changed concern the backport, I disable monitor interface in AP mode to solve the connection problem in a channel using DFS and it doesn't concern your firmware.
Another thing that I've mentioned in my mail before that my AP create this interface when my station connected to my AP:
Interface wlan0.sta1                                                   
                ifindex 10                                                     
                wdev 0x6                                                       
                addr 04:f0:21:0e:38:be                                         
                type AP/VLAN                                                   
                channel 36 (5180 MHz), width: 40 MHz, center1: 5190 MHz
I am wrong because if I set up Router network for my STA, my AP won't create the interface wlan.sta1 when my STA connect, but if my STA is set up in Bridge network, the interface wlan0.sta1 will be created so this doesn't concern your firmware too.
