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.

Use the AP_MAX_LINKS as the upper boundary for traversing the links array,
thereby guaranteeing BA sessions with all connected STAs are stopped when
the stop_ba event is received.

Unblock the RX BA constraint event from firmware in AP mode as well.
This allows us to stop RX BA sessions when the FW requests it.
In addition refactor the handler for this event to make the flow
clearer.

Change the commands and events according to the new fw api
(fw >= 6/7.3.0.0.75).
The main change is the replacement of JOIN/DISCONNECT commands,
with ROLE_START/ROLE_STOP commands.
The use of these commands should be preceded by the ROLE_ENABLE
command (allocating role resources), and followed by the
ROLE_DISABLE command (freeing role resources).

Beacon early termination doesn't help much in the 5GHz band and masks

When rx_streaming.interval is non-zero, use automatic rx streaming.
Enable rx streaming on the each rx/tx packet, and disable it
rx_streaming.duration msecs later.
When rx_streaming.always=0 (default), rx streaming is enabled only
when there is a coex operation.

In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events.
Both are reported to the upper layers as a TX failure in the offending
stations.
In STA mode we register only for the MAX_TX_RETRY event. A TX failure is
interpreted as a loss of connection.
Support for IEEE80211_HW_REPORTS_TX_ACK_STATUS has been removed to avoid
the inherent race condition of a mac80211 TX failure counter in addition
to the FW counter.
This patch depends on "mac80211: allow low level driver to report packet
loss"

ELP (Extremely/Enhanced Low Power, or something like that ;)) refers to
the powerstate of the 12xx chip, in which very low power is consumed,
and no commands (from the host) can be issued until the chip is woken up.
Wakeup/sleep commands must be protected by a wl->mutex, so it's generally
a good idea to call wakeup/sleep along with the mutex lock/unlock (where
needed). However, in some places the wl12xx driver calls wakeup/sleep in
some "inner" functions. This result in some "nested" wakeup/sleep calls
which might end up letting the chip go to sleep prematurely (e.g. during
event handling).
Fix it by rearranging the elp calls to come along with mutex_lock/unlock.

Support sending dummy packet to wl128x FW as results of
dummy packet event. That is part of dynamic TX mem blocks mechanism.
Only send dummy packet when not in AP mode.
[Even though the DUMMY_PACKET_EVENT_ID and the
STA_REMOVE_COMPLETE_EVENT_ID events are defined to the same value, we
need to treat them separately in the code. Keep the check and enable
STA_REMOVE_COMPLETE_EVENT_ID for AP mode and DUMMY_PACKET_EVENT_ID for
STA. Moved one warning to a cleaner place. Use WL1271_TID_MGMT for
dummy packets -- Luca]

This patch adds support for the new wl12xx firmware (Rev 6.1.3.50.49)
Since this fw is not backward compatible with previous fw versions,
a new fw (with different name) is being fetched.
(the patch is big because it contains all the required fw api changes.
splitting it into multiple patches will result in corrupted intermediate
commits)

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:
