6 GHz regulatory domains introduces Power Spectral Density (PSD).
The PSD value of the regulatory rule should be taken into effect
for the ieee80211_channels falling into that particular regulatory
rule. Save the values in the channel which has PSD value and add
nl80211 attributes accordingly to handle it.

If the driver doesn't fill NL80211_STA_INFO_TX_BITRATE in sta_set_sinfo()
then as a fallback sta->deflink.tx_stats.last_rate is used. Unfortunately
there's no guarantee that this has actually been set before it's used.
Originally found when 'iw <dev> link' would always return a tx rate of
6Mbps regardless of actual link speed for the QCA9337 running firmware

cfg80211 has cfg80211_chandef_dfs_usable() function to know whether
at least one channel in the chandef is in usable state or not. Also,
cfg80211_chandef_dfs_cac_time() function is there which tells the CAC
time required for the given chandef.
Make these two functions visible to drivers by exporting their symbol
to global list of kernel symbols.
Lower level drivers can make use of these two functions to be aware
if CAC is required on the given chandef and for how long. For example
drivers which maintains the CAC state internally can make use of these.

Currently the channel property updates are not propagated to
driver. This causes issues in the discovery of hidden SSIDs and
fails to connect to them.
This change defines a new wiphy flag which when enabled by vendor
driver, the reg_call_notifier callback will be trigger on beacon
hints. This ensures that the channel property changes are visible
to the vendor driver. The vendor changes the channels for active
scans. This fixes the discovery issue of hidden SSID.

This commit implements defer setup support for the Broadcast Sink
scenario: By setting defer setup on a broadcast socket before calling
listen, the user is able to trigger the PA sync and BIG sync procedures
separately.
This is useful if the user first wants to synchronize to the periodic
advertising transmitted by a Broadcast Source, and trigger the BIG sync
procedure later on.
If defer setup is set, once a PA sync established event arrives, a new
hcon is created and notified to the ISO layer. A child socket associated
with the PA sync connection will be added to the accept queue of the
listening socket.
Once the accept call returns the fd for the PA sync child socket, the
user should call read on that fd. This will trigger the BIG create sync
procedure, and the PA sync socket will become a listening socket itself.
When the BIG sync established event is notified to the ISO layer, the
bis connections will be added to the accept queue of the PA sync parent.
The user should call accept on the PA sync socket to get the final bis
connections.

mlx5 MACsec RoCEv2 support
From Patrisious:
This series extends previously added MACsec offload support
to cover RoCE traffic either.
In order to achieve that, we need configure MACsec with offload between
the two endpoints, like below:
REMOTE_MAC=10:70:fd:43:71:c0
* ip addr add 1.1.1.1/16 dev eth2
* ip link set dev eth2 up
* ip link add link eth2 macsec0 type macsec encrypt on
* ip macsec offload macsec0 mac
* ip macsec add macsec0 tx sa 0 pn 1 on key 00 dffafc8d7b9a43d5b9a3dfbbf6a30c16
* ip macsec add macsec0 rx port 1 address $REMOTE_MAC
* ip macsec add macsec0 rx port 1 address $REMOTE_MAC sa 0 pn 1 on key 01 ead3664f508eb06c40ac7104cdae4ce5
* ip addr add 10.1.0.1/16 dev macsec0
* ip link set dev macsec0 up
And in a similar manner on the other machine, while noting the keys order
would be reversed and the MAC address of the other machine.
RDMA traffic is separated through relevant GID entries and in case
of IP ambiguity issue - meaning we have a physical GIDs and a MACsec
GIDs with the same IP/GID, we disable our physical GID in order
to force the user to only use the MACsec GID.

The commit 14af9963ba ("bonding: Support macvlans on top of tlb/rlb mode
bonds") aims to enable the use of macvlans on top of rlb bond mode. However,
the current rlb bond mode only handles ARP packets to update remote neighbor
entries. This causes an issue when a macvlan is on top of the bond, and
remote devices send packets to the macvlan using the bond's MAC address
as the destination. After delivering the packets to the macvlan, the macvlan
will rejects them as the MAC address is incorrect. Consequently, this commit
makes macvlan over bond non-functional.
To address this problem, one potential solution is to check for the presence
of a macvlan port on the bond device using netif_is_macvlan_port(bond->dev)
and return NULL in the rlb_arp_xmit() function. However, this approach
doesn't fully resolve the situation when a VLAN exists between the bond and
macvlan.
So let's just do a partial revert for commit 14af9963ba in rlb_arp_xmit().
As the comment said, Don't modify or load balance ARPs that do not originate
locally.

Don't queue more gc work, else we may queue the same elements multiple
times.
If an element is flagged as dead, this can mean that either the previous
gc request was invalidated/discarded by a transaction or that the previous
request is still pending in the system work queue.
The latter will happen if the gc interval is set to a very low value,
e.g. 1ms, and system work queue is backlogged.
The sets refcount is 1 if no previous gc requeusts are queued, so add
a helper for this and skip gc run if old requests are pending.

While looking at a bug, I got rather confused by the layout of the
'status' field in ieee80211_tx_info. Apparently, the intention is that
status_driver_data[] is used for driver specific data, and fills up the
size of the union to 40 bytes, just like the other ones.
This is indeed what actually happens, but only because of the
combination of two mistakes:
- "void *status_driver_data[18 / sizeof(void *)];" is intended
to be 18 bytes long but is actually two bytes shorter because of
rounding-down in the division, to a multiple of the pointer
size (4 bytes or 8 bytes).
- The other fields combined are intended to be 22 bytes long, but
are actually 24 bytes because of padding in front of the
unaligned tx_time member, and in front of the pointer array.
The two mistakes cancel out. so the size ends up fine, but it seems
more helpful to make this explicit, by having a multiple of 8 bytes
in the size calculation and explicitly describing the padding.

UDP sendmsg() is lockless, so ip_select_ident_segs()
can very well be run from multiple cpus [1]
Convert inet->inet_id to an atomic_t, but implement
a dedicated path for TCP, avoiding cost of a locked
instruction (atomic_add_return())
Note that this patch will cause a trivial merge conflict
because we added inet->flags in net-next tree.
v2: added missing change in

veth and vxcan need to make sure the ifindexes of the peer
are not negative, core does not validate this.
Using iproute2 with user-space-level checking removed:
Before:
# ./ip link add index 10 type veth peer index -1
# ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

Now:
$ ./ip link add index 10 type veth peer index -1
Error: ifindex can't be negative.
This problem surfaced in net-next because an explicit WARN()
was added, the root cause is older.

Given a macsec net_device add two functions to return the real net_device
for that device, and check if that macsec device is offloaded or not.
This is needed for auxiliary drivers that implement MACsec offload, but
have flows which are triggered over the macsec net_device, this allows
the drivers in such cases to verify if the device is offloaded or not,
and to access the real device of that macsec device, which would
belong to the driver, and would be needed for the offload procedure.

LWTUNNEL_XMIT_CONTINUE is implicitly assumed in ip(6)_finish_output2,
such that any positive return value from a xmit hook could cause
unexpected continue behavior, despite that related skb may have been
freed. This could be error-prone for future xmit hook ops. One of the
possible errors is to return statuses of dst_output directly.
To make the code safer, redefine LWTUNNEL_XMIT_CONTINUE value to
distinguish from dst_output statuses and check the continue
condition explicitly.
