zero rx_filter_enabled array after recovery to avoid
cases were the driver will keep trying to clear a
filter which is not configured in FW.
Such case will cause consecutive recoveries due to
command execution failures.
While on it, convert rx_filter_enabled to bitmap,
to save some memory and make sparse happy (it
doesn't like sizeof(bool array)).

Sometimes a tx_flush during suspend fails, but the FW manages to flush
out the packets during the time when the host is supsended. Cancel
the Tx-watchdog on suspend to not cause a spurious recovery on resume
for that case. Set a flag to reinit the watchdog on the first Tx after
resume, so we'll still recover if the FW is not empty and there's
indeed a problem.

It seems the wl18xx FW sometimes sends spurious changes on the PSM state
of the broadcast HLID. This causes us to search for a station on a
non-peer link and fail, causing warnings in our log.
Prevent the driver from considering PSM changes for any non-peer HLIDs.

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.

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).

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.

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.

disassoc, when wlvif->sta.hlid, resulting in invalid

Some fields are missing from the event mailbox

Add the missing fields in order to align the
