I probably tweaked this patch since sending.  my wave-1 didn't work with this approach,
and in the end, to get a valid RSSI, I ended up reading the
per-chain noise-floor periodically and storing that so I could use proper noise-floor
instead of just -95.  I am not sure upstream firmware can support that, so probably
not worth adding just the sum logic unless someone can figure out how to get the noise
floor out of the firmware...
