Currently we're setting the sta->addr as the peers address only if
the iftype is NL80211_IFTYPE_AP, otherwise we are setting the bssid to
be the addr. This causes bugs in TDLS. Fix this by always using the
sta->addr.

During CSA the PHY used by the link is changing, So the driver
needs to modify the links phy to the FW. Currently the driver is doing
it by removing the link and adding a new one with the new phy_id, but the
FW expects the link only to be modified. Fix this by modifying the links

I.e. - we can't send one of the new cmds and then one of the old ones.
This will cause a FW assert. So we need an indication what API should be
used. We use the new API if:
1. FW supports it
2. We are registered to mac80211 with the new MLD ops

In MLO, some fields of iwl_mvm_vif should be defined in the
context of a link. Define a separate structure for these fields and
add a deflink object to hold it as part of iwl_mvm_vif. Non-MLO legacy
code will use only deflink object while MLO related code will use the
corresponding link from the link array.
It follows the strategy applied in mac80211 for introducing MLO
changes.
The below spatch takes care of updating all driver code to access

GCC has optimizations for division by a constant that clang does not

Use the 64-bit division helper div_u64(), which takes a u64 dividend and

As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of a nontransmitted
BSSID profile, an EMA AP that transmits a Beacon frame carrying a partial
list of nontransmitted BSSID profiles should include in the frame
a Reduced Neighbor Report element carrying information for at least the
nontransmitted BSSIDs that are not present in the Multiple BSSID element
carried in that frame.
Add new nested attribute NL80211_ATTR_EMA_RNR_ELEMS to support the above.
Number of RNR elements must be more than or equal to the number of
MBSSID elements. This attribute can be used only when EMA is enabled.
Userspace is responsible for splitting the RNR into multiple elements such
that each element excludes the non-transmitting profiles already included
in the MBSSID element (%NL80211_ATTR_MBSSID_ELEMS) at the same index.
Each EMA beacon will be generated by adding MBSSID and RNR elements
at the same index. If the userspace provides more RNR elements than the
number of MBSSID elements then these will be added in every EMA beacon.

Previously, fast xmit only worked on interface types where initially a
sta lookup is performed, and a cached header can be attached to the sta,
requiring only some fields to be updated at runtime.
This technique is not directly applicable for a mesh device type due
to the dynamic nature of the topology and protocol. There are more
addresses that need to be filled, and there is an extra header with a
dynamic length based on the addressing mode.
Change the code to cache entries contain a copy of the mesh subframe header +
bridge tunnel header, as well as an embedded struct ieee80211_fast_tx, which
contains the information for building the 802.11 header.
Add a mesh specific early fast xmit call, which looks up a cached entry and
adds only the mesh subframe header, before passing it over to the generic
fast xmit code.
To ensure the changes in network are reflected in these cached headers,
flush affected cached entries on path changes, as well as other conditions
that currently trigger a fast xmit check in other modes (key changes etc.)
This code is loosely based on a previous implementation by:

We have a new STA cmd as part of the new MLD API. There are some
parts of sending the STA cmd which are common to both the old and
the new one. Put this parts in functions which will later be used
to send the new STA cmd.

As the new MLD API is introduced, we have a new enumeration
for the different station types. Since struct iwl_mvm_sta's
sta_type field will be in use for both new and old API,
change its type to a unified one, so it can hold both.

This function sends the STA_HE_CTXT_CMD, which won't be used in the
new MLD API. Instead, a part of the fields of this command
will be in the new STA cmd. Put the parts that are common to both
commands in functions, which will later be used in sending the new
STA cmd.

We used to send a MAC CTXT cmd to ask the FW to not pass MCAST frames
if we're associated but not authorized, because we don't have the
keys in that stage, and after authorization - we sent the cmd again
to ask the FW to pass MCAST, as we have the keys now.
The patch linked below was changing this strategy to always allow
MCAST frames, and if we're not authorized - the driver will drop them.
But we're still sending the MAC CTXT cmd after deaouthorization even
though we don't tell the FW to not pass MCAST frames anymore.
Basically we don't tell the FW anything new with this cmd.
Fix this by not sending MAC CTXT command after deauthorization.
For authorization we're sending the cmd to configure other changes too,
so keep it.

This is another patch in the series adding all the ops
for the new MLD ieee80211_ops.

iwl_mvm_get_sync_time() reads the gp2 from the device and then
reads the system clock. Since the two reads are not done atomically,
unexpected delays may happen between the two reads (e.g. context
switch) which make it inaccurate.
In order to improve the accuracy of the cross timestamp, call
iwl_mvm_get_sync_time() multiple times in a loop and take the
result in which the difference between the two clock is the smallest.
