On many different chips, important aspects of the MAC state are not fully cleared by a warm reset. This can show up as tx/rx hangs, those annoying "DMA failed to stop in 10 ms..." messages or other quirks. On AR933x, the chip can occasionally get stuck in a way that only a driver unload/reload or a reboot would bring it back to life. With this patch, a full reset is issued when bringing the chip out of FULL-SLEEP state (after idle), or if either Rx or Tx was not shut down properly. This makes the DMA related error messages disappear completely in my tests on AR933x, and the chip does not get stuck anymore.
