rtlwifi: Fix error registering rate-control

When a second module such as rtl8192ce or rtl8192cu links to rtlwifi, the attempt
to register a rate-control mechanism fails with the warning shown below. The fix is to
select the RC mechanism when rtlwifi is initialized.

iwlwifi: fix dma mappings and skbs leak

Since commit commit 470058e0ad82fcfaaffd57307d8bf8c094e8e9d7
"iwlwifi: avoid Tx queue memory allocation in interface down" we do

mac80211: support direct offchannel TX offload

For devices supported by iwlwifi sometimes
off-channel transmissions need to be handled
by the device completely. To support this
mac80211 needs to pass the frame directly
to the driver and not through the TX path
as the driver needs the frame and channel
information at the same time.

There is a race on sending a data frame before the tx completion

follows the nullfunc frame, the AP thinks that the station is out

wl12xx: AP-mode - support HW based link PS monitoring

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.

Report a TX rate idx of -1 and count 0 when returning untransmitted
skbs to mac80211 using ieee80211_tx_status(). Otherwise mac80211
tries to use the returned (essentially garbage) status.

wl12xx: AP-mode - TX queue per link in AC

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.

wl12xx: AP-mode - fix race condition on sta connection

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.

wl12xx: fix potential race condition with TX queue watermark

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.

wl12xx: declare support for IEEE80211_HW_REPORTS_TX_ACK_STATUS

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

Since we do the rate control in the fw, we'll probably want

account for retransmissions as well.

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

rt2x00: Minor optimization for devices with RTS/CTS offload

Only devices that don't have RTS/CTS offload need to check for
IEEE80211_TX_RC_USE_RTS_CTS and IEEE80211_TX_RC_USE_CTS_PROTECT.

By swapping both conditions we keep the same number of needed conditionals
for devices without RTS/CTS offload but save one conditional on devices
with RTS/CTS offload.
