a790cc3a4f 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.

0ff57171d6 cfg80211: Update Transition Disable policy during port authorization
In case of 4way handshake offload, transition disable policy
updated by the AP during EAPOL 3/4 is not updated to the upper layer.
This results in mismatch between transition disable policy
between the upper layer and the driver. This patch addresses this
issue by updating transition disable policy as part of port
authorization indication.

e8d0b807b4 wifi: mac80211: remove support for AddBA with fragmentation
HE added support for dynamic fragmentation inside aggregation
sessions, but no existing driver ever advertises it. Thus,
remove the code for now, it cannot work as-is in MLO. For it
to properly work in MLO, we'd need to validate that the frag
level is identical across all the link bands/iftypes, which
is a good amount of complex code that's just not worth it as
long as no driver has support for it.

2e82be13c6 wifi: mac80211: agg-rx: avoid band check
If the deflink of the station is on 6 GHz, then it won't have HT.
If at the same time we're using MLO, then vif.bss_conf isn't used,
and thus vif.bss_conf.chandef.chan is NULL, causing the code to
crash.

Fix this by just checking for both HT and HE, and refusing the
aggregation session if both are not present. This might be a bit
wrong since it would accept an aggregation session from a peer
that has HE but no HT on 2.4 or 5 GHz, but such a peer shouldn't
exist in the first place, and it probably supports aggregation if
it has HE support.

45ebac4f05 wifi: mac80211: Parse station profile from association response
When processing an association response frame for a Multi-Link
connection, extract the per station profile for each additional
link, and use it for parsing the link elements.

As the Multi-Link element might be fragmented, add support for
reassembling a fragmented element. To simplify memory management
logic, extend 'struct ieee802_11_elems' to hold a scratch buffer,
which is used for the defragmentation. Once an element is
reconstructed in the scratch area, point the corresponding element
pointer to it. Currently only defragmentation of Multi-Link element
and the contained per-STA profile subelement is supported.

8af9d4068e wifi: atmel: Avoid clashing function prototypes
When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].

Of the 1549 warnings found, 188 come from the atmel driver. For example:

drivers/net/wireless/atmel/atmel.c:2518:2: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, void *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict]
        (iw_handler) atmel_config_commit,       /* SIOCSIWCOMMIT */
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The atmel Wireless Extension handler callbacks (iw_handler) use a union
for the data argument. Actually use the union and perform explicit
member selection in the function body instead of having a function
prototype mismatch. There are no resulting binary differences.

This patch is a cleanup based on Brad Spengler/PaX Team's modifications
to the atmel driver in their last public patch of grsecurity/PaX based
on my understanding of the code. Changes or omissions from the original
code are mine and don't reflect the original grsecurity/PaX code.

62ccb2e6f2 brcmfmac: Fix authentication latency caused by OBSS stats survey
Auto Channel Select feature of HostAP uses dump_survey to fetch
OBSS statistics. When the device is in the middle of an authentication
sequence or just at the end of authentication completion, running
dump_survey would trigger a channel change. The channel change in-turn
can cause packet loss, resulting in authentication delay. With this change,
dump_survey won't be run when authentication or association is in progress,
hence resolving the issue.

216647e6aa brcmfmac: fix firmware trap while dumping obss stats
When doing dump_survey, host will call "dump_obss" iovar to firmware
side. Host need to make sure the HW clock in dongle is on, or there is
high probability that firmware gets trap because register or shared
memory access failed. To fix this, we disable mpc when doing dump obss
and set it back after that.

6c04deae14 brcmfmac: Add dump_survey cfg80211 ops for HostApd AutoChannelSelection
To enable ACS feature in Hostap daemon, dump_survey cfg80211 ops and dump
obss survey command in firmware side are needed. This patch is for adding
dump_survey feature and adding DUMP_OBSS feature flag to check if
firmware supports dump_obss iovar.

791082ec0a wifi: rtl8xxxu: gen2: Turn on the rate control
Re-enable the function rtl8xxxu_gen2_report_connect.

It informs the firmware when connecting to a network. This makes the
firmware enable the rate control, which makes the upload faster.

It also informs the firmware when disconnecting from a network. In the
past this made reconnecting impossible because it was sending the
auth on queue 0x7 (TXDESC_QUEUE_VO) instead of queue 0x12
(TXDESC_QUEUE_MGNT):

wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 1/3)
wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 2/3)
wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 3/3)
wlp0s20f0u3: authentication with 90:55:de:__:__:__ timed out

Probably the firmware disables the unnecessary TX queues when it
knows it's disconnected.

However, this was fixed in commit edd5747aa12e ("wifi: rtl8xxxu: Fix
skb misuse in TX queue selection").

Fixes: c59f13bbead4 ("rtl8xxxu: Work around issue with 8192eu and 8723bu devices not reconnecting")
