These patches add access point mode support to the wl12xx driver.
This mode uses a separate firmware and has a different initialization
sequence.
In all instances, the flow has been split according to the operating
mode of the driver (AP/STA), so as not to affect STA mode functionality.
v1->2: rebased on latest wl12xx tree
v2->3: refactoring
v3->4: cross-patch fix
Arik Nemtsov (18):
wl1271: Add AP related configuration to conf_drv_settings
wl1271: AP mode - AP specific CMD_CONFIGURE sub-commands
wl1271: AP mode - add AP specific event
wl1271: AP-mode high level commands
wl1271: AP mode - workaround for FW bug on station remove
wl1271: AP mode - init sequence
wl1271: AP specific RX filter configuration
wl1271: Add AP related definitions to HOST-FW interface

wl1271: AP mode config in ieee80211_ops.config
wl1271: AP mode - change filter config
wl1271: AP mode - add STA add/remove ops
wl1271: AP mode - changes in TX path
wl1271: AP mode - record TX configuration settings
wl1271: AP mode - encryption support
wl1271: AP mode - fetch appropriate firmware for AP
wl1271: Read MAC address from NVS file on HW startup
wl1271: Enable AP-mode

1.7.1
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.

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.

1.7.1
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).

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.

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).
