@anchao Thank you for the code changes. I've applied them locally and it

613Kb/s is not all that speedy, but at least it ran error free. And I'll
note, I'm not fully sure what a good metric is for this chip.
Thanks again, let me know what other debugs/tests I can perform.
That sdio_io_rw_extended error upon boot persists. I also discovered that
the wlan0 interface appears to "go to sleep" at some point of inactivity and
does not wake back up:

The two pings were separated by ~10mins of idle time. Not sure what's up
there, but it's been consistently loosing network ability after a period of
time. wapi shows that the "SENSE" value goes from -58 to 0.
