The firmware WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1 often stops sending
data on 5GHz when SU support is advertised. A simple throughput benchmark
will end up at only a couple hundred kilobytes per second (when finishing
at all).

Disabling SU related flags works around this problem and allowed a maximum
throughput of ~450 MBit/s in a simple test setup with an HK01 over air.
