We are introducing a new structure, mt792x_link_sta, to manage per-link
configurations in preparation for future station (STA) support of
Multi-Link Operation (MLO).
This patch only includes structural changes and does not involve any
logic changes.
We have moved relevant parameters, such as the wcid from the mt76_wcid
structure, from the mt7921x_sta structure to the mt792x_link_sta structure.
For current drivers that do not support MLO, there is only one link STA,
and link information is accessed via the deflink member.
However, we have not yet created the per-link BSS configuration indexed
by link ID for Multi-Link Device (MLD) support in mt7921x_sta.
This step needs to be completed before adding MLD support for STA mode.

We are introducing a new structure, mt792x_bss_conf, to manage per-link
configurations in preparation for future STA support of Multi-Link
Operation (MLO).
The patch does not include any logic changes, only structural changes.
We have moved relevant parameters from the mt7921x_vif structure such
as to mt76 of mt76_vif structure, rssi and Tx queue parameters to
mt7921x_bss_conf structure. We can access those members to configure the
BSS for this interface, whether it is our own BSS or the one we are
associated with.
However, we have not yet created the per-link BSS configuration indexed by
link ID for Multi-Link Device (MLD) support. This step needs to be
extended before adding MLD support for AP mode.

The firmware support for management frame protection has limitations:
- do not support cipher BIP-GMAC-128 and BIP-GMAC-256
- support cipher BIP-CMAC-128 and BIP-CMAC-256, except action frame with
action type 'not robust'.
Therefore, to simplify the logic, do not set the IGTK to firmware and
let the encryption of management frames be handled by upper layer.

During chip recovery (e.g. chip reset), there is a possible situation that
kernel worker reset_work is holding the lock and waiting for kernel thread
stat_worker to be parked, while stat_worker is waiting for the release of

It causes a deadlock resulting in the dumping of hung tasks messages and
possible rebooting of the device.
