When operating in AP mode the wl1271 hardware filters out null-data
packets as well as management packets. This makes it impossible for
mac80211 to monitor the PS mode by using the PM bit of incoming frames.
Disable mac80211 automatic link PS-mode handling by supporting
IEEE80211_HW_AP_LINK_PS in HW flags.

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.

add the IEEE80211_HW_REPORTS_TX_ACK_STATUS flag to our supported

account for retransmissions as well.
