When operating in AP-mode we require a per link tx-queue.
This allows us to implement HW assisted PS mode for links,
as well as regulate per-link FW TX blocks consumption.
Split each link into ACs to support future QoS for AP-mode.

AC queues are emptied in priority and per-link queues are
scheduled in a simple round-robin fashion.

If a sta starts transmitting immediately after authentication, sometimes
the FW deauthenticates it. Fix this by marking the sta "in-connection"
in FW before sending the autentication response.

The "in-connection" entry is automatically removed when connection
succeeds or after a timeout.

Check the conditions for the high/low TX queue watermarks when the
spin-lock is taken. This prevents race conditions as tx_queue_count and
the flag checked are only modified when the spin-lock is taken.

The following race was in mind:
- Queues are almost full and wl1271_op_tx() will stop the queues, but it
  doesn't get the spin-lock yet.
- (on another CPU) tx_work_locked() dequeues 15 skbs from this queue and
  tx_queue_count is updated to reflect this
- wl1271_op_tx() does not check tx_queue_count after taking the
  spin-lock and incorrectly stops the queue.

The wl12xx fw supports ack status reporting for tx frames, so
add the IEEE80211_HW_REPORTS_TX_ACK_STATUS flag to our supported
features.

Since we do the rate control in the fw, we'll probably want
to adjust the STA_LOST_PKT_THRESHOLD heuristics in the future, to
account for retransmissions as well.

for debugging purposes, wl12xx determines whether a rx packet
is a beacon packet.

however, it checks only the frame_control subtype without checking
the actual packet type, which leads to false identification in some
cases.
