ath9k: Fix PS mode operation to receive buffered broadcast/multicast frames
The previous implementation was moving back to NETWORK SLEEP state immediately after receiving a Beacon frame. This means that we are unlikely to receive all the buffered broadcast/multicast frames that would be sent after DTIM Beacon frames. Fix this by parsing the Beacon frame and remaining awake, if needed, to receive the buffered broadcast/multicast frames. The last buffered frame will trigger the move back into NETWORK SLEEP state. If the last broadcast/multicast frame is not received properly (or if the AP fails to send it), the next Beacon frame will work as a backup trigger for returning into NETWORK SLEEP. A new debug type, PS (debug=0x800 module parameter), is added to make it easier to debug potential power save issues in the future. Currently, this is only used for the Beacon frame and buffered broadcast/multicast receiving. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.
