Raspberry Pi 3 WiFi - TurboQAM Support

[sfx2000]

Might have been below the radar scope of many, but finding TurboQAM clients can be a challenge...

The Pi 3 includes the BCM43438 WiFi/BT combo chip - while it's single stream, and 20MHz only, it supposedly supports TurboQAM for a 96Mbps bandwidth at the PHY...

Anyone with a Broadcom based AC1900-class BHR with Turbo support try this?

The other interesting tidbit in the Broadcom driver included with the Raspian Jessie kernel...

I'll need to dig a bit into this one, but I thought I would share... I know what it is - WiFi Direct, but I'm not seeing the upper layer stuff in the kernel - that's why it's interesting...

BTW - if you want to find your PI's on the LAN... use ARP...

arp -a | grep b8:27:eb | grep -Eo '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'
