NL80211_HIDDEN_SSID_NOT_IN_USE is zero but prefer

says that bit 0 of the CRC7 code must always be a 1.
I confirmed that today with a logic analyzer: setting bit 0 causes
wilc1000 to accept a command with CRC7 enabled, whereas clearing bit 0
causes wilc1000 to reject the command with a CRC error.

During mac80211 reconfig, chanctx ops of multiple channels might not
be called in order as normal cases. However, we expect the first active
chanctx always to be put at our sub entity index 0. So, if it does not,
we do a swap there. Besides, reconfig won't allocate a new chanctx object.
So, we should reset the reference count when ops add chanctx.

After MLO, we will need to consider not only active chanctx but also active
interfaces (roles) to decide entity things. So in advance, we move handling
from chanctx_ops::add/remove to chanctx_ops::assign_vif/unassign_vif. Then,
we can recalculate and aware active interfaces' changes.
For now, behavior should not be really different, since active chanctx and
active interface are one-to-one mapping before MLO.

Originally, we consider weight only based on how many chanctxs that
mac80211 sets. However, we need to consider both active chanctxs and
active interfaces to distinguish MCC (multiple channel concurrent)
from impending MLO.
Although the logic of handling is extended, for now, behavior might
not be different under current condition.

Originally, we just declared two sub-entity, and according to rolling
down mechanism, we ensured that index 0 contained sub-entity as long
as there are sub-entity. So, we could use for-loop after deciding the
last index.
But, we are preparing to expand num of sub-entity for MLO. Then, there
won't be just two sub-entity. And, there might be holes between two bits
in the bitmap. So, we cannot simply do for-loop as before. Instead, we
need to follow the set bits.

Some of our calculation during concurrent mode depend on last beacon
TSF. Originally, we just set IEEE80211_HW_TIMING_BEACON_ONLY and get
what we want from mac80211. But, IEEE80211_HW_TIMING_BEACON_ONLY will
be restricted once we declare MLO.
Since we are about to consider the MLO stuffs, so sync beacon TSF by
ourselves now and unset IEEE80211_HW_TIMING_BEACON_ONLY.

WILC driver currently applies some default configuration whenever the firmware
is initialized, and sets the default preamble size to short. However, despite
this passed option, firmware is also able to successfully connect to access
points only using long preamble, so this setting does not really enforce short
preambles and is misleading regarding applied configuration.
Update default configuration and make it match the firmware behavior by passing
the existing WILC_FW_PREAMBLE_AUTO value (2 instead of 0). The updated setting
does not really alter firmware behavior since it is still capable to connect to
both short preamble and long preamble access points, but at list the setting now
expresses for real the corresponding firmware behavior.
More info: it has been implemented to address the transmission (Tx) blackout
issue observed in the 802.11b mode. The modification has no impact on the other
modes, which will continue to work as they did in the previous implementation.
This change will allow the 802.11b transmission (2, 5.5, 11Mbps) to use long
preamble.

The firmware (later) actually uses the values even for keys
that are invalid as far as the host is concerned, later in
rekeying, and then only sets the low 48 bits since the PNs
are only 48 bits over the air. It does, however, compare the
full 64 bits later, obviously causing problems.
Remove the memset and use kzalloc instead to avoid any old
heap data leaking to the firmware. We already init all the
other fields in the struct anyway. This leaves the data set
to zero for any unused fields, so the firmware can look at
them safely even if they're not used right now.

When retrieving the queue index ("SCD SSN") from the TX response,
it's currently masked with 0xFFF. However, now that we have queues
longer than 4k, that became wrong, so make the mask depend on the
hardware family.
This fixes an issue where if we get a single frame reclaim while
in the top half of an 8k long queue, we'd reclaim-wrap the queue
twice (once on this and then again on the next non-single reclaim)
which at least triggers the WARN_ON_ONCE() in iwl_txq_reclaim(),
but could have other negative side effects (such as unmapping a
frame that wasn't transmitted yet, and then taking an IOMMU fault)
as well.
