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.

wifi: mt76: mt792x: add struct mt792x_bss_conf

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.

Merge tag 'rtw-next-2024-07-05' of https://github.com/pkshih/rtw

rtw-next patches for v6.11

Some cleanups of rtl8xxxu and rtlwifi, and some fixes of rtw88. The major
change is to develop WoWLAN and preparation of RTL8852BE-VT listed below:

rtw89:
  - preparation of RTL8852BE-VT
    * add RF calibration code
    * move shared code with RTL8852BE to common module
  - add WoWLAN for WiFi 6 chips
  - support 36-bit PCI DMA

wifi: ipw2x00: Use kzalloc() instead of kmalloc()/memset()

Replace kmalloc() + memset() to kzalloc() for
better code readability and simplicity.

wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()

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:

wifi: cfg80211: add support for advertising multiple radios belonging to a wiphy

The prerequisite for MLO support in cfg80211/mac80211 is that all the links
participating in MLO must be from the same wiphy/ieee80211_hw. To meet this
expectation, some drivers may need to group multiple discrete hardware each
acting as a link in MLO under single wiphy.

With this change, supported frequencies and interface combinations of each
individual radio are reported to user space. This allows user space to figure
out the limitations of what combination of channels can be used concurrently.

Even for non-MLO devices, this improves support for devices capable of
running on multiple channels at the same time.

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.

wifi: rtw88: usb: schedule rx work after everything is set up

Right now it's possible to hit NULL pointer dereference in
rtw_rx_fill_rx_status on hw object and/or its fields because
initialization routine can start getting USB replies before
rtw_dev is fully setup.

The stack trace looks like this:

rtw_rx_fill_rx_status
rtw8821c_query_rx_desc
rtw_usb_rx_handler
...
queue_work
rtw_usb_read_port_complete
...
usb_submit_urb
rtw_usb_rx_resubmit
rtw_usb_init_rx
rtw_usb_probe

So while we do the async stuff rtw_usb_probe continues and calls
rtw_register_hw, which does all kinds of initialization (e.g.
via ieee80211_register_hw) that rtw_rx_fill_rx_status relies on.

Fix this by moving the first usb_submit_urb after everything
is set up.

For me, this bug manifested as:
[    8.893177] rtw_8821cu 1-1:1.2: band wrong, packet dropped
[    8.910904] rtw_8821cu 1-1:1.2: hw->conf.chandef.chan NULL in rtw_rx_fill_rx_status
because I'm using Larry's backport of rtw88 driver with the NULL
checks in rtw_rx_fill_rx_status.

wifi: mac80211: remove DEAUTH_NEED_MGD_TX_PREP

This flag is annoying because it puts a lot of logic into mac80211
that could just as well be in the driver (only iwlmvm uses it) and
the implementation is also broken for MLO.

Remove the flag in favour of calling drv_mgd_prepare_tx() without
any conditions even for the deauth-while-assoc case. The drivers
that implement it can take the appropriate actions, which for the
only user of DEAUTH_NEED_MGD_TX_PREP (iwlmvm) is a bit more tricky
than the implementation in mac80211 is anyway, and all others have
no need and can just exit if info->was_assoc is set.

wifi: nl80211: don't give key data to userspace

When a key is requested by userspace, there's really no need
to include the key data, the sequence counter is really what
userspace needs in this case. The fact that it's included is
just a historic quirk.

Remove the key data.

net: thunderx: Unembed netdev structure

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_devices from struct lmac by converting them
into pointers, and allocating them dynamically. Use the leverage
alloc_netdev() to allocate the net_device object at
bgx_lmac_enable().

The free of the device occurs at bgx_lmac_disable().

 Do not free_netdevice() if bgx_lmac_enable() fails after lmac->netdev
is allocated, since bgx_lmac_disable() is called if bgx_lmac_enable()
fails, and lmac->netdev will be freed there (similarly to lmac->dmacs).
