7a0501d20d AP MLD: Refresh beacons for other links when one gets disabled/enabled
If one or more BSS from the interface is partnering with BSSs from
another interface and if this interface gets disabled, the Beacon frames
need to be refreshed for other interfaces. Similar thing should happen
when it gets enabled.

Add logic to refresh other interface Beacon frames when one of the
interfaces is disabled or enabled.

d2b62b3fe5 AP MLD: Support link removal before removing interface
Previously, whenever if_remove() was called, the whole interface was
deleted. In an AP MLD, all partner BSS use the same driver private
context and hence removing the interface when only one of the links goes
down should be avoided.

Add a helper function to remove a link first whenever if_remove() is
called. Later while handling it, if the number of active links goes to
0, if_remove() would be called to clean up the interface.

This helper function will be used later when co-hosted AP MLD support is
added and as well later during ML reconfiguration support.

55c30e8aba nl80211: Remove AP MLD links while removing the interface
When the interface was removed, the added links were not removed. While
removing the interface, kernel has removed the stale links but hostapd
has not. This is wrong since hostapd should remove and do the clean ups
properly while removing the interface.

Hence, remove the links when interface is removed.

b162886fd0 nl80211: Re-factor nl80211_remove_links() function
nl80211_remove_links() iterated over all active links in the given BSS
and removed all of them. However, at times it is required to remove only
one link and not all links.

Add a helper function nl80211_remove_link() which will remove just the
given link_id from the passed BSS. nl80211_remove_links() will use this
and will call this for each of the active links to be removed.

60e1dca1ef AP MLD: Clean up MLD when not required any further
Currently, whenever a new BSS is created, if it is an EHT BSS it is tied
to a corresponding MLD structure. If the structure does not exist
already, a new one is created and tied to it. Accordingly, the link ID
is assigned as well. However, when the BSS is deleted, the MLD structure
is not freed and when it is again created the next time, the link ID is
incremented further and the BSS gets a wrong link ID.

For example, 2.4 GHz single link AP MLD case: First ADD, link ID 0 would
be assigned and MLD interface wlan0 would be created. When REMOVE is
issued, the BSS would be deleted but MLD wlan0 will not. When ADD is
issued again, the BSS will tie back to MLD wlan0 but this time the link
ID will be incremented again and 1 would be assigned. Hence, at
subsequent REMOVE/ADD, the link ID keeps on incrementing.

Since the link ID remains same for the full lifetime of the BSS and MLD,
the next link ID counter cannot be just reset back to 0 when a BSS is
deleted. Otherwise, in interleaved link enable/disable case, the link ID
would be changed.

To overcome this situation, whenever a BSS is deleted, if the MLD is not
referenced by any other existing BSS, delete the MLD structure itself.

To know how many BSSs are referring a given MLD, introduce a new member
refcount in MLD. If the value is 0 it is safe to delete the MLD.

fac34688ad AP MLD: Assign link ID during BSS creation
Link ID was assigned when BSS is going through setup and the driver
interface init. Later if interface is disabled and enabled again, setup
BSS is called which will give a new link ID to it. However, Link ID
should be same for a BSS affliated to an AP MLD for the full lifetime of
the BSS.

Hence, assign the link ID during BSS creation itself. And it will remain
until BSS entry is completely freed. Hence, link ID will not change as
part of disable/enable.

Also, since link ID would be decided now, it will help in creating link
level control sockets in a subsequent patch.

2f0e5303e8 AP MLD: Add a separate MLD level structure
MLD level information like MLD MAC address, next link ID, etc. was
stored in each BSS. However, only the first link BSS assigns values to
these members and the other link BSSs store references to the first BSS.
However, if the first BSS is disabled, the first BSS reference in all
BSS should be updated which is an overhead. Also, this does not seem to
scale.

Instead, a separate MLD level structure can be maintained which can
store all this ML related information. All affiliated link BSSs can keep
reference to this MLD structure.

This commit adds that MLD level structure. However, assigning values to
it and using that instead of BSS level members will be done in
subsequent commits.

259b43a31a hostapd: MLO: Avoid use of mld_id as user configuration
mld_id was provided as a user configuration to identify partner BSS
belonging to the same AP MLD. The same id is used at the protocol level
also to indicate the AP MLD ID of the MLD.

But, in general mld_id is a relative reference of the MLD where 0 is
used as the mld_id to represent the self MLD and in case of MLO MBSSID
mld_id of a non transmitted BSS affiliated to an AP MLD is based on the
relative BSS index of the non transmitted BSS from the transmitted BSS.
Hence mld_id need not be fetched from users, rather it can be identified
wherever required.

To verify if the partners belong to the same AP MLD the interface name
can be checked, since all link BSS partners of the same AP MLD belong to
the same interface.

Hence, remove use of mld_id user config and instead introduce two
functions hostapd_is_ml_partner() and hostapd_get_mld_id(). The former
is used to verify whether partners belong to the same AP MLD and the
latter is used to get the MLD ID of the BSS.

9be122d2e0 nl80211: Fix AP MLD frequency update on channel switch
mlme_event() calls nl80211_get_link_id_by_freq() to determine the link
to handle reported events. However, in channel switch event it is always
setting freq to the default link that leads to the issue that all other
events that go to mlme_event() will be handled in the default link.

Fix this by setting freq to the correct link specified by the link ID
when processing the event for a completed channel switch.

8d0bd7f9c8 Update BSS entry on roaming only for actual BSS frequency change
Commit 117e812d06 ("Update BSS table entry if roaming event indicates
frequency change") added wpa_supplicant BSS table update based on the
latest driver scan results whenever processing an association event that
results in the current operating channel changing. While that is needed
to cover the case where an AP changes its own operating channel (and
that is noticed as a roam or new connection instead of a channel switch
event), this should not really be needed for cases where the
wpa_supplicant entry for the new BSS is already up to date.

Skip the full BSS table update on association event if the event is for
a roaming case to a different BSS and the BSS entry for the target is
already available and for the current operating channel. This avoids
undesired latency when processing the association event.
