performance of the Gigabit FEC is limited to 400Mbps (total for Tx and Rx)
* When using softAP mode on Band A on the Qualcomm AR6233, channels used for
Dynamic Frequency Selection (DFS) are not supported
* The Qualcomm AR6233 firmware does not support the following configuration
modes:
  * Concurrent modes involving P2P mode, such as P2P + softAP or P2P + STA
  * Bluetooth + softAP + STA concurrent mode
* A maximum of five clients are supported when using Qualcomm's AR6233 in
softAP mode
