694440d93b wl12xx: disable AP-mode-specific quirks
The current wl12xx fw (7.3.0.0.77) supports both STA and AP mode, and
we no longer use AP-mode-specific quirks.

WL12XX_QUIRK_END_OF_TRANSACTION is still used for certain HWs, while
WL12XX_QUIRK_LPD_MODE is not used anymore.

6d158ff38d wl12xx: Add support for HW channel switch
The wl12xx FW supports HW channel switch.  If we don't use it,
sometimes the firmware gets confused when recalibrating to the new
channel, causing RX problems.  This commit adds HW channel switch
support by implementing the channell_switch op.

4b29886feb wl12xx: configure rate policy for p2p operations
p2p packets should go out only with OFDM rates.

Configure a new rate policy that will (later) be used
during p2p_find (when the p2p_cli / p2p_go interfaces
are in use, we won't have to use this policy, as
the configured rates should already be OFDM-only).

Additionally, update CONF_TX_MAX_RATE_CLASSES to reflect

26b4bf2e0f wl12xx: remove P2P ie from probe response
wl12xx uses a single probe response template, regardless of
the probe request.
However, the P2P spec forbids including the p2p ie in some
cases (e.g. the probe request didn't include the p2p ie).

The fw responds only to probe requests that don't
include the p2p ie, and passes up probe requests that
include them (the supplicant will answer them).

Thus, strip the p2p ie from the probe response template.

f952079a19 wl12xx: add support for multiple SSIDs in sched_scan
The wl12xx firmwares support multiple SSIDs in a single sched_scan

We use three different types os sched_scan: FILTER_ANY (ie. not

probe_reqs with the specified SSIDs and only report if they are
found); and FILTER_DISABLED (ie. send out probe_reqs with the
specified SSIDs, but report anything found).

Since we still don't have proper filter support in nl80211/cfg80211
yet, we cannot use filters when the wildcard SSID is used.  Thus, we
will not filter anything if the wildcard SSID is specified.
