If we just check "result & RX_DROP_UNUSABLE", this really only works
by accident, because SKB_DROP_REASON_SUBSYS_MAC80211_UNUSABLE got to
have the value 1, and SKB_DROP_REASON_SUBSYS_MAC80211_MONITOR is 2.
Fix this to really check the entire subsys mask for the value, so it
doesn't matter what the subsystem value is.

The commit 06470f7468 ("mac80211: add API to allow filtering frames in BA sessions")
added reorder_buf_filtered to mark frames filtered by firmware, and it
can only work correctly if hw.max_rx_aggregation_subframes <= 64 since
it stores the bitmap in a u64 variable.
However, new HE or EHT devices can support BlockAck number up to 256 or
1024, and then using a higher subframe index leads UBSAN warning:
UBSAN: shift-out-of-bounds in net/mac80211/rx.c:1129:39

It can be really hard to analyse or debug why packets are
going missing in mac80211, so add the needed infrastructure
to use use the new per-subsystem drop reasons.
We actually use two drop reason subsystems here because of
the different handling of frames that are dropped but still
go to monitor for old versions of hostapd, and those that
are just completely unusable (e.g. crypto failed.)
Annotate a few reasons here just to illustrate this, we'll
need to go through and annotate more of them later.

If a packet has reached its intended destination, it was bumped to the code

Previously, fast xmit only worked on interface types where initially a
sta lookup is performed, and a cached header can be attached to the sta,
requiring only some fields to be updated at runtime.
This technique is not directly applicable for a mesh device type due
to the dynamic nature of the topology and protocol. There are more
addresses that need to be filled, and there is an extra header with a
dynamic length based on the addressing mode.
Change the code to cache entries contain a copy of the mesh subframe header +
bridge tunnel header, as well as an embedded struct ieee80211_fast_tx, which
contains the information for building the 802.11 header.
Add a mesh specific early fast xmit call, which looks up a cached entry and
adds only the mesh subframe header, before passing it over to the generic
fast xmit code.
To ensure the changes in network are reflected in these cached headers,
flush affected cached entries on path changes, as well as other conditions
that currently trigger a fast xmit check in other modes (key changes etc.)
This code is loosely based on a previous implementation by:

When we have multiple interfaces receiving the same frame,
such as a multicast frame, one interface might have a sta
and the other not. In this case, link_sta would be set but
not cleared again.
Always set link_sta, so we keep an invariant that link_sta
and sta are either both set or both not set.

There's at least one case in ieee80211_rx_for_interface()
where we might pass &((struct sta_info *)NULL)->sta to it
only to then do container_of(), and then checking the
result for NULL, but checking the result of container_of()
for NULL looks really odd.
Fix this by just passing the struct sta_info * instead.

The ieee80211_accept_frame() function performs a number of early checks
to decide whether or not further processing needs to be done on a frame.
One of those checks is the ieee80211_is_robust_mgmt_frame() function.
It requires to peek into the frame payload, but because defragmentation
does not occur until later on in the receive path, this peek is invalid
for any fragment other than the first one. Also, in this scenario there
is no STA and so the fragmented frame will be dropped later on in the
process and will not reach the upper stack. This can happen with large
action frames at low rates, for example, we see issues with DPP on S1G.
This change will only check if the frame is robust if it's the first
fragment. Invalid fragmented packets will be discarded later after
defragmentation is completed.

Non-MLO station frames are dropped in Rx path due to the condition
check in ieee80211_rx_is_valid_sta_link_id(). In multi-link AP scenario,
non-MLO stations try to connect in any of the valid links in the ML AP,
where the station valid_links and link_id params are valid in the
ieee80211_sta object. But ieee80211_rx_is_valid_sta_link_id() always
return false for the non-MLO stations by the assumption taken is
valid_links and link_id are not valid in non-MLO stations object
(ieee80211_sta), this assumption is wrong. Due to this assumption,
non-MLO station frames are dropped which leads to failure in association.
Fix it by removing the condition check and allow the link validation
check for the non-MLO stations.

At least ath10k and ath11k supported hardware (maybe more) does not implement
mesh A-MSDU aggregation in a standard compliant way.
802.11-2020 9.3.2.2.2 declares that the Mesh Control field is part of the
A-MSDU header (and little-endian).
As such, its length must not be included in the subframe length field.
Hardware affected by this bug treats the mesh control field as part of the
MSDU data and sets the length accordingly.
In order to avoid packet loss, keep track of which stations are affected
by this and take it into account when converting A-MSDU to 802.3 + mesh control
packets.

The current mac80211 mesh A-MSDU receive path fails to parse A-MSDU packets
on mesh interfaces, because it assumes that the Mesh Control field is always
directly after the 802.11 header.
802.11-2020 9.3.2.2.2 Figure 9-70 shows that the Mesh Control field is
actually part of the A-MSDU subframe header.
This makes more sense, since it allows packets for multiple different
destinations to be included in the same A-MSDU, as long as RA and TID are
still the same.
Another issue is the fact that the A-MSDU subframe length field was apparently
accidentally defined as little-endian in the standard.
In order to fix this, the mesh forwarding path needs happen at a different
point in the receive path.
ieee80211_data_to_8023_exthdr is changed to ignore the mesh control field
and leave it in after the ethernet header. This also affects the source/dest
MAC address fields, which now in the case of mesh point to the mesh SA/DA.
ieee80211_amsdu_to_8023s is changed to deal with the endian difference and
to add the Mesh Control length to the subframe length, since it's not covered
by the MSDU length field.
With these changes, the mac80211 will get the same packet structure for
converted regular data packets and unpacked A-MSDU subframes.
The mesh forwarding checks are now only performed after the A-MSDU decap.
For locally received packets, the Mesh Control header is stripped away.
For forwarded packets, a new 802.11 header gets added.
