Fix: Order of assignments is now correct, after being incorrect
due to an incorrect merge between
https://codereview.webrtc.org/2617373002/ and
https://codereview.webrtc.org/2589713003.
Improvement: Set parameters in more places, allowing for
correct reconfiguration. Add TODOs to point of minor issues
with current configuration.
TESTED=By locally patching an application using this code.
