To: linux-wireless; +Cc: Luciano Coelho, Arik Nemtsov
Add commands to start/stop BSS, add/remove STA and configure encryption
keys. Split the encryption commands "set key" and "set default key" into
AP and STA specific versions.

Sometimes an event indicating station removal is not sent up by
firmware. We work around this by always indicating success in when
a wait for the event timeouts.
Temporary workaround until a FW fix is introduced.

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.

Allocate and free host link IDs (HLIDs) for each link. A per-STA
data structure keeps the HLID of each STA.

When in AP mode set appropriate HLID and rate policy for each skb.
Respond to supported-rates related changes in op_tx only when acting
as STA.

Record TX configuration settings in the "conf" member of our global
structure (struct wl1271) if conf_tx is called when the firmware is
not loaded.
Later on when the firmware is loaded, we apply the tx conf as part of
the init sequence.
Important for AP mode since conf_tx is called before add_interface
(where the firmware is initialized).

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).

AP and STA modes use different firmwares.
Differentiate the firmware files by name and fetch the appropriate one
when add_interface is called by mac80211. The STA firmware is chosen for
PLT mode.

Try to read the MAC address from the on-disk NVS file.
A non-zero MAC address is required to add an AP interface.
