a8c0ddb5ba 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.

99a2775d02 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.

72c2d9e511 wl12xx: set supported_rates after association
Instead of looking for supported_rates change on every tx packet,
just extract the supported_rates after association completes (station only).

Remove wl1271.sta_rate_set and WL1271_FLAG_STA_RATES_CHANGED which are
not used anymore.

7f179b4689 wl12xx: AP mode - encryption support
Encryption key configuration is different for AP/STA modes.

AP encryption keys are recorded when the BSS is not started. On BSS
start they are propagated to the AP (in wl1271_ap_init_hwenc).

e0fe371b74 wl12xx: AP mode - init sequence
Split HW init sequence into AP/STA specific parts

The AP specific init sequence includes configuration of templates, rate
classes, power mode, etc. Also unmask AP specific events in the event mbox.

Separate the differences between AP and STA init into mode
specific functions called from wl1271_hw_init. The first is called after
radio configuration and the second after memory configuration.

6742f554db wl12xx: Change TX queue to be per AC
With the current single-queue implementation traffic priorization is not
working correctly - when using multiple BE streams and one, say VI stream,
the VI stream will share bandwidth almost equally with the BE streams.

To fix the issue, implement per AC queues, which are emptied in priority
order to the firmware. To keep it relatively simple, maintain a global
buffer count and global queue stop/wake instead of per-AC.

With these changes, priorization appears to work just fine.

2f01a1f588 wl12xx: add driver
wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded
devices, supporting both SDIO and SPI busses. Currently the driver
supports only SPI. Adding support 1253 (the 5 GHz version) should be
relatively easy. More information here:
