From: Sriram R <quic_srirrama@xxxxxxxxxxx>
To prepare the driver for MLO support, split the driver vif
data structure to scale for multiple links. This requires changing
the use of arvif to per link and not per hw which can now
comprise of multiple links.
Also since most configurations from mac80211 are done per link, do refactoring
of the driver functions to apply these configurations at link level.
Split ath12k_vif which is the driver private of ieee80211_vif to store
link specific information as ath12k_link_vif. For default use cases
the ath12k vif will have a preallocated link vif called deflink which will
be used by non ML and the first link vif of ML vif.
With MLO Support to be added, remaining link vifs will be allocated during
channel assignment where vdev create/start happens. These link vifs will be
freed during interface down.
Current ath12k_vif(arvif) structure

Proposed ath12k_vif(ahvif) containing ath12k_link_vif(s) (arvif)

ieee80211_vif is MLD and is the only link otherwise)

+---------------------------------+
To refactor existing ath12k_vif to make use of link vifs, following
changes are made,
1. ath12k_vif now called by variable name ahvif stores multiple
arvifs(ah12k_link_vif) and also has a back pointer to ieee80211_vif.
2. In this patch set, only deflink is used to be on par with the
existing code. When MLO support is added the link id will be used to
fetch the arvif.
3. For mac80211 ops which doesn't use specific link_id, the config or info
is common for the vif, hence apply the config to all link vifs.
The links_map in the ahvif, will be used to identify all the link vifs that
are setup.
4. Change ath12k_vif_to_arvif() as ath12k_vif_to_ahvif() to fetch the
hw level vif. The link vif can be fetched from ahvif->link[], or the
deflink can be accessed via ahvif->deflink. API to access link
vif(arvif) by passing link_id can be introduced with MLO Support.
5. The ieee80211_vif can be accessed from ahvif using ath12k_vif_to_vif()
Locking:
Currently modifications to members of arvif and arsta are protected by ar->conf_mutex
and it stays as such.
Now with these hw level structure (ahvif) being introduced, any modifications
to its members and link objects (i.e., arvifs[] which are dynamically allocated)
needs to be protected for writing and ah->conf_mutex is used for the same.
Also, atomic contexts(say WMI events and certain mac_ops) that we currently have in driver
will not(shouldn't be allowed) do any modifications but can read them and
rcu_read_lock() is used for the same.
