高通QCA9880无线板卡使用ath10k驱动，5GHz 的AP模式无法跑起来

[liqq88]

开发板为NXP下的LS1012ARDB，使用LSDK1809工程，在内核中配置cfg80211和mac80211驱动，加上高通QCA9880网卡的ath10k驱动，编译后运行，sta模式运行正常，连接到5G路由器速度到867M，但是5G的AP模式带宽只有20Mhz，速度很低，需求是带宽达到80MHz，速度为867M。hostapd的配置文件参考https://wireless.wiki.kernel.org/en/users/Drivers/ath10k/configuration中的Example hostapd config to use 11ac VHT80 mode with ath10k。
以下为摘录hostapd启动无线的操作，有能解答的，重谢！！
