lockdep complains use of uninitialized spinlock at ieee80211_do_stop() [1],

fq_init() from ieee80211_txq_setup_flows() initializes this spinlock.
According to discussion [2], Toke was not happy with expanding usage of
fq.lock. Since __ieee80211_wake_txqs() is called under RCU read lock, we
can instead use synchronize_rcu() for flushing ieee80211_wake_txqs().

It might seem a bit pointless to do a multi-link operation
connection with just a single link, but this is already a
big change, so for now, limit MLO connections to a single
link.
Extending that to multiple links will require
* work on parsing the multi-link element with STA profile
properly, including element fragmentation;
* checking the per-link status in the multi-link element
* implementing logic to have active/inactive links to let
drivers decide which links should be active;
* implementing multicast RX deduplication;
* and likely more.
For now this is still useful since it lets us do multi-link
connections for the purposes of testing APIs and the higher
layers such as wpa_supplicant.

When parsing a frame containing a multi-BSSID element, we
need to know both the transmitted and non-transmitted BSSID
so we can parse it correctly.
Unfortunately, in quite a number of cases, we got this wrong
and were passing the wrong BSSID or useless information:
* the mgmt->bssid from a frame is only the transmitted
BSSID if the frame is a beacon
* passing just one of the parameters as non-NULL isn't
useful and ignored
In those case where we need to parse for a specific BSS we
always have a BSS structure pointer, representing the BSS
we need, whether transmitted or not. Thus, pass that pointer
to the parsing function instead of the two BSSIDs.
Also fix two bugs:
* we need to re-parse all the elements for the other BSS
when iterating the non-transmitted BSSes in scan
* we need to parse for the correct BSS when setting up
the channel data in client code

In AP mode, multicast traffic is handled very differently from normal traffic,
especially if at least one client is in powersave mode.
This means that multicast packets can be buffered a lot longer than normal
unicast packets, and can eat up the AQL budget very quickly because of the low
data rate.
Along with the recent change to maintain a global PHY AQL limit, this can lead
to significant latency spikes for unicast traffic.

center_freq and center_freq1 need to be recalculated.
There is a typo in the case of downgrading bandwidth from
320MHz to 160MHz which would cause a wrong frequency value.

When a client does not generate any local tx activity, accumulating airtime

In order to maintain fairness, the amount of queueing needs to be limited
beyond the simple per-station AQL budget, otherwise the driver can simply
repeatedly do scheduling rounds until all queues that have not used their
AQL budget become eligble.
To be conservative, use the high AQL limit for the first txq and add half
of the low AQL for each subsequent queue.

When queueing packets for a station, deficit only gets added once the packets
have been transmitted, which could be much later. During that time, a lot of

This reverts commits 6a789ba679 and

The virtual time scheduler code has a number of issues:
- queues slowed down by hardware/firmware powersave handling were not properly
handled.
- on ath10k in push-pull mode, tx queues that the driver tries to pull from
were starved, causing excessive latency
- delay between tx enqueue and reported airtime use were causing excessively
bursty tx behavior
The bursty behavior may also be present on the round-robin scheduler, but there
it is much easier to fix without introducing additional regressions

For rate control, at least initially we won't support it in MLO,

In order to support multi-link operation with multiple links,
start adding some APIs. The notable addition here is to have
the link ID in a new nl80211 attribute, that will be used to
differentiate the links in many nl80211 operations.
So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID
attribute (as well as the NL80211_ATTR_MLO_LINKS attribute)
and plugs it through the system in some places, checking the
validity etc. along with other infrastructure needed for it.
For now, I've decided to include only the over-the-air link
ID in the API. I know we discussed that we eventually need to
have to have other ways of identifying a link, but for local
AP mode and auth/assoc commands as well as set_key etc. we'll
use the OTA ID.
Also included in this patch is some refactoring of the data

In ieee80211_vif_use_reserved_context(), when we have an
old context and the new context's replace_state is set to
IEEE80211_CHANCTX_REPLACE_NONE, we free the old context
in ieee80211_vif_use_reserved_reassign(). Therefore, we
cannot check the old_ctx anymore, so we should set it to
NULL after this point.
However, since the new_ctx replace state is clearly not
IEEE80211_CHANCTX_REPLACES_OTHER, we're not going to do
anything else in this function and can just return to
avoid accessing the freed old_ctx.
