We are introducing a new structure, mt792x_chanctx, to quickly identify
the linked BSS it is working on. This eliminates the need to search in
mt7921_ctx_iter() or mt7925_ctx_iter() when the channel context changes.

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.

This issue has not been identified earlier because tests were done on
a device with SMP disabled and so spinlocks were actually NOPs.
Now use spin_(un)lock_bh for TX queue related locking to avoid execution
of softirq work synchronously that would lead to a deadlock.

In rvu_check_rsrc_availability() in case of invalid SSOW req, an incorrect

'req->ssow'. Looks like "copy-paste" mistake.
Fix this mistake by replacing 'req->sso' with 'req->ssow'.

mwifiex_get_priv_by_id() returns the priv pointer corresponding to
the bss_num and bss_type, but without checking if the priv is actually
currently in use.
Unused priv pointers do not have a wiphy attached to them which can
lead to NULL pointer dereferences further down the callstack. Fix
this by returning only used priv pointers which have priv->bss_mode
set to something else than NL80211_IFTYPE_UNSPECIFIED.
Said NULL pointer dereference happened when an Accesspoint was started
with wpa_supplicant -i mlan0 with this config:
network={
ssid="somessid"
mode=2
frequency=2412
key_mgmt=WPA-PSK WPA-PSK-SHA256
proto=RSN
group=CCMP
pairwise=CCMP
psk="12345678"
}
When waiting for the AP to be established, interrupting wpa_supplicant
with <ctrl-c> and starting it again this happens:

bnxt doesn't check if a ring is used by RSS contexts when reducing
ring count. Core performs a similar check for the drivers for
the main context, but core doesn't know about additional contexts,
so it can't validate them. bnxt_fill_hw_rss_tbl_p5() uses ring
id to index bp->rx_ring[], which without the check may end up
being out of bounds.

sa8775p-ride-r3
On sa8775p-ride-r3 the RX clocks from the AQR115C PHY are not available at
the time of the DMA reset. We can however extract the RX clock from the
internal SERDES block. Once the link is up, we can revert to the
previous state.
The AQR115C PHY doesn't support in-band signalling so we can count on
getting the link up notification and safely reuse existing callbacks
which are already used by another HW quirk workaround which enables the
functional clock to avoid a DMA reset due to timeout.
Only enable loopback on revision 3 of the board - check the phy_mode to
make sure.

When user issues a connection with a different SSID than the one
virt_wifi has advertised, the __cfg80211_connect_result() will
trigger the warning: WARN_ON(bss_not_found).
The issue is because the connection code in virt_wifi does not
check the SSID from user space (it only checks the BSSID), and
virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS
even if the SSID is different from the one virt_wifi has advertised.
Eventually cfg80211 won't be able to find the cfg80211_bss and generate
the warning.
Fixed it by checking the SSID (from user space) in the connection code.

Manivannan writes:
MHI Host
========
- Used unique 'mhi_pci_dev_info' struct for product families instead of reusing
a shared struct. This allows displaying the actual product name for the MHI
devices during driver probe.
- Added support for Foxconn SDX72 based modems, T99W515 and DW5934E.
- Added a 'name' field to 'struct mhi_controller' for allowing the MHI client
drivers to uniquely identify each MHI device based on its product/device name.
This is useful in applying any device specific quirks in the client drivers.
WWAN MHI Client driver
======================
- Due to the build dependency with the MHI patch exposing 'name' field to client
drivers, the WWAN MHI client driver patch that is making use of the 'name'
field to apply custom data mux id for Foxconn modems is also included.
Collected Ack from Networking maintainer for this patch.
MHI EP
======
- Fixed the MHI EP stack to not allocate memory for MHI objects from DMA zone.
This was done accidentally while adding the slab cache support and causes the
MHI EP stack to run out of memory while doing high bandwidth transfers.

This patch expands PSE callbacks with newly introduced
pi_get/set_current_limit() and pi_get_voltage() callback.
It also add the power limit ranges description in the status returned.
The only way to set ps692x0 port power limit is by configure the power
class plus a small power supplement which maximum depends on each class.

This patch add a way to get and set the power limit of a PSE PI.
For that it uses regulator API callbacks wrapper like get_voltage() and
get/set_current_limit() as power is simply V * I.
We used mW unit as defined by the IEEE 802.3-2022 standards.
set_current_limit() uses the voltage return by get_voltage() and the
desired power limit to calculate the current limit. get_voltage() callback
is then mandatory to set the power limit.
get_current_limit() callback is by default looking at a driver callback
and fallback to extracting the current limit from _pse_ethtool_get_status()
if the driver does not set its callback. We prefer let the user the choice
because ethtool_get_status return much more information than the current
limit.
expand pse status with c33_pw_limit_ranges to return the ranges available
to configure the power limit.
