wifi: mac80211: simplify non-chanctx drivers

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the
channel context handling.

wifi: mac80211: add wake_tx_queue callback to drivers

mac80211 is fully switching over to the internal TX queue (iTXQ)
implementation. Update all drivers not yet providing the now mandatory
wake_tx_queue() callback.

As an side effect the netdev interfaces of all updated drivers will
switch to the noqueue qdisc.

mac80211: prepare sta handling for MLO support

Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.

With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.

To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.

For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.

For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.

Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.

Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

mwl8k: Use named struct for memcpy() region

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.

Use named struct in struct mwl8k_cmd_set_key around members key_material,
tkip_tx_mic_key, and tkip_rx_mic_key so they can be referenced
together. This will allow memcpy() and sizeof() to more easily reason
about sizes, improve readability, and avoid future warnings about writing
beyond the end of key_material.

"pahole" shows no size nor member offset changes to struct
mwl8k_cmd_set_key. "objdump -d" shows no object code changes.

mwl8k: Fix use-after-free in mwl8k_fw_state_machine()

When the driver fails to request the firmware, it calls its error
handler. In the error handler, the driver detaches device from driver
first before releasing the firmware, which can cause a use-after-free bug.

Fix this by releasing firmware first.

mwl8k: Fix a double Free in mwl8k_probe_hw

In mwl8k_probe_hw, hw->priv->txq is freed at the first time by
dma_free_coherent() in the call chain:
if(!priv->ap_fw)->mwl8k_init_txqs(hw)->mwl8k_txq_init(hw, i).

Then in err_free_queues of mwl8k_probe_hw, hw->priv->txq is freed
at the second time by mwl8k_txq_deinit(hw, i)->dma_free_coherent().

My patch set txq->txd to NULL after the first free to avoid the
double free.

hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'mwl8k_rxq_init()' and 'mwl8k_txq_init()'
GFP_KERNEL can be used because this flag is already used in a 'kcalloc()'
call, just a few line below.

When memory is allocated in 'mwl8k_firmware_load_success()' GFP_KERNEL can
be used because this flag is already used within 'ieee80211_register_hw()'
which is called just a few line below.

# 17481234 07-May-2020 Gustavo A. R. Silva <gustavoars@kernel.org>

mwl8k: Replace zero-length array with flexible-array

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
int stuff;
struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

mac80211: simplify TX aggregation start

There really is no need to make drivers call the
ieee80211_start_tx_ba_cb_irqsafe() function and then
schedule the worker if all we want is to set a bit.

Add a new return value (that was previously considered
invalid) to indicate that the driver is immediately
ready for the session, and make drivers use it. The
only drivers that remain different are the Intel ones
as they need to negotiate more with the firmware.

mwl8k: Fix rate_idx underflow

It was reported on OpenWrt bug tracking system[1], that several users
are affected by the endless reboot of their routers if they configure
5GHz interface with channel 44 or 48.

The reboot loop is caused by the following excessive number of WARN_ON
messages:

WARNING: CPU: 0 PID: 0 at backports-4.19.23-1/net/mac80211/rx.c:4516
ieee80211_rx_napi+0x1fc/0xa54 [mac80211]

as the messages are being correctly emitted by the following guard:

case RX_ENC_LEGACY:
if (WARN_ON(status->rate_idx >= sband->n_bitrates))

as the rate_idx is in this case erroneously set to 251 (0xfb). This fix
simply converts previously used magic number to proper constant and
guards against substraction which is leading to the currently observed
underflow.

mac80211: clean up rate encoding bits in RX status

In preparation for adding support for HE rates, clean up
the driver report encoding for rate/bandwidth reporting
on RX frames.

Much of this patch was done with the following spatch:

wireless: Set NL80211_EXT_FEATURE_CQM_RSSI_LIST in multiple drivers

Set the NL80211_EXT_FEATURE_CQM_RSSI_LIST wiphy extended feature
wholesale in all mac80211-based drivers that do not set the
IEEE80211_VIF_BEACON_FILTER flags on their interfaces. mac80211 will
be processing supplied RSSI values in ieee80211_rx_mgmt_beacon and
will detect when the thresholds set by
ieee80211_set_cqm_rssi_range_config are crossed. Remaining (few)
drivers need code to enable the firmware to monitor the thresholds.
This is mostly only compile-tested.

cfg80211: remove enum ieee80211_band

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

mac80211: pass block ack session timeout to to driver

Currently mac80211 does not inform the driver of the session
block ack timeout when starting a rx aggregation session.
Drivers that manage the reorder buffer need to know this
parameter.
Seeing that there are now too many arguments for the
drv_ampdu_action() function, wrap them inside a structure.
