Some fields are missing from the event mailbox
struct definitions, which cause issues when
trying to handle some events.
Add the missing fields in order to align the
struct size (without adding actual support
for the new fields).

Bump the min wl18xx fw version to 8.8.0.0.13
This fw is not backward compatible with older
firmware (due to api changes), so use bump
the firmware name as well.
Some modifications were done to the driver-fw api
in order to support multiple APs.
Additionally, some of the consts (such as max stations,
max links and max RX BA sessions) were changed.

Each hw supports a different iface combinations.
Define the supported combinations in each driver,
and save it in wl->iface_combinations.
Since each driver defines its own combinations now,
it can also define its max supported channels, so
we no longer need to save and set it explicitly
in wlcore.
Update wl18xx interface combinations to allow
multiple APs.

Upcoming fw versions will have different max links support
(according to the hw). Get ready for it by configuring
wl->num_links per-hw, instead of using the const WL12XX_MAX_LINKS.
However, continue using WLCORE_MAX_LINKS in order to simplify
structs declarations (we use it in multiple bitmaps, and converting
them to dynamic arrays is just cumbersome).

Instead of splitting the fw_status into 2 and using some
complex calculations, read the fw status and let each low-level
driver (wl12xx/wl18xx) convert it into a common struct.
This is required for the upcoming fw api changes, which
break the current logic anyway.

In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.
PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).
This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.
The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.
The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:
1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock

Add support for the secondary channel offset IE in channel
switch announcements. This is necessary for proper handling
of CSA on HT access points.
For this to work it is also necessary to convert everything
here to use chandef structs instead of just channels. The
driver updates aren't really correct though. In particular,
the TI wl18xx driver update can't possibly be right since
it just ignores the new channel width for lack of firmware
API.

For VHT, many more bandwidth changes are possible. As a first
step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag
in the HT capabilities and instead introduce a bandwidth field
indicating the currently usable bandwidth to transmit to the
station. Of course, make all drivers use it.
To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get
the station as an argument, rather than the new capabilities,
so it can set up the new bandwidth field.
If the station is a VHT station and VHT bandwidth is in use,
also set the bandwidth accordingly.
Doing this allows us to get rid of the supports_40mhz flag as
the HT capabilities now reflect the true capability instead of
the current setting.
While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not
ignore HT cap overrides when MCS TX isn't supported (not that it
really happens...)

Update the 18xx FW status private part to include Tx related link
priorities. Introduce new HW ops to determine link priority per chip
family.
For 18xx the changes are:
- Suspended links are at most low priority and Tx for them is stopped
beyond the suspend threshold.
- Active links now get their thresholds directly from FW
- There's a new "stop" threshold for active links, at which point a link
stops receiving new packets.
Update the min 18xx FW version required to make sure suspended links
bitmap is advertised by the FW.

There's a limit on scan dwell times of max 30ms in order
to avoid degrading voip traffic which could be going on
while scanning. However these dwell times increase the
chance of missing out on nearby APs leading to partial
scan results. Allow configuration of longer dwell times
in case there no active interface (i.e. no STA associated
or AP up).

Prioritize EDCA by choosing the AC before anything else. Use the
fast/slow link bitmap in FW to improve the scheduling algorithm for
the multi-link scenario.
Set packet thresholds to determine if a given link is high or low
priority according to its speed. A slow link will be given high priority
if the amount of packets queued for it in the FW is lower than the
slow-threshold. Similarly, a fast link will be given high priority if
the number of its packets queued in FW is smaller than the high-threshold.
The improved algorithm:
1. Choose optimal AC according to FW utilization
2. Traversing the VIFs in a round-robin fashion, try to choose a high
priority link. Links are traversed in a round-robin fashion inside a
VIF.
3. If no high priority links are found, choose the first non-empty
(low priority) link found in the round robin.

In 18xx the calibration process of the PHY Cortex domain
requires to perform an active calibration of the channel
before it can be used for transmission. To fulfill world
wide regulatory restrictions, fw should be always
synchronized/updated with current CRDA configuration.
Add a new "CMD_DFS_CHANNEL_CONFIG" command to update the
fw with current reg-domain, this command passes a bit map
of channels that are allowed to be used for transmission.
The driver shall update the fw during initialization and
after each change in the current reg-domain
configuration. The driver will save the channel number of
incoming beacons during the scan process, as they might
be a result of the passive scan on
"IEEE80211_CHAN_PASSIVE_SCAN" channel and will update the
fw accordingly once the scan is finished, the purpose of
this is to be ready in case of the authentication request
on one of these disabled (uncalibrated) channels.
The new command requires to wait for the fw completion
event "DFS_CHANNELS_CONFIG_COMPLETE_EVENT".
No scan commands (including the sched scan) can be
executed concurrently with the "CMD_DFS_CHANNEL_CONFIG",
wl->mutex ensures that.
