Support for Netgear R8300

I purchased a modern router that was on sale without thinking to confirm support with open source firmware. I'm curious if there is support for the Netgear R8300 which is using the Broadcom BCM47094 CPU and Broadcom BCM4366 wireless.

I realize now after buying this that there is very little Broadcom support due to the nature of drivers being closed sourced.

You are lucky and both SoC and Wireless IC are actually supported.
So in theory R8300 could be supported
