Ok, I will look at the 59th commit today.

As for commit 172, it should be virtually identical to the firmware-2-ct-non-commercial.bin

I will double-check that I didn't miss some commit.

Can you try each of these and let me know if they work for promisc mode?

And, in case it's a bit of a race, maybe try rebooting with each firmware
several times to see if it works in promisc sometimes and not others?
