With the latest iw from the git repo I get:

                VHT Capabilities (0x038071a0):
                        Max MPDU length: 3895
                        Supported Channel Width: neither 160 nor 80+80
                        short GI (80 MHz)
                        TX STBC
                        SU Beamformee
                VHT RX MCS set:
                        1 streams: MCS 0-9
                        2 streams: MCS 0-9
                        3 streams: not supported
                        4 streams: not supported
                        5 streams: not supported
                        6 streams: not supported
                        7 streams: not supported
                        8 streams: not supported
                VHT RX highest supported: 0 Mbps
                VHT TX MCS set:
                        1 streams: MCS 0-9
                        2 streams: MCS 0-9
                        3 streams: not supported
                        4 streams: not supported
                        5 streams: not supported
                        6 streams: not supported
                        7 streams: not supported
                        8 streams: not supported
                VHT TX highest supported: 0 Mbps

Is it OK that it is reporting  "VHT TX highest supported: 0 Mbps" ?
