Subject: brcmfmac driver with CYW4373E, MCS rate table, statistics, and performance

Greetings,

Is there a way to get the MCS rate table and stats from the brcmfmac driver?

I have a CYW4373E based 802.11ac SDIO module and am wondering what
others have gotten for infrastructure throughput on this chip. I'm
seeing about 270mbps in AP mode with MCS9 (MCS rate verified by client
side device). I'm guessing the much lower than (theoretical) 433mbps
rate I'm getting is a factor of the SDIO bus (which is running at
208MHz SDR104).

Best Regards,

Tim
