Hm... Did you actually hit this if?
I am not sure I really want to wait here (which is what will happen if
you return false) when we get an unexpected length? I do not expect
anything besides the response I am waiting for since the firmware is
handling the GET_STATUS *only* - it just came back from WoWLAN. Bottom
line, this is really an error path and I prefer to exit and not wait for
the timeout in that case.
But I might be missing something?
