This reverts commit c37ce764cd492f044dcdbb39616298f02b0dbc7f.
RCCL library is currently not treating spatial partitions differently,
hence this change is causing issues. Revert temporarily till RCCL
implementation is ready for spatial partitions.

[Why]
Some older MST hubs do not report DPCD registers according to
specification.
[How]
This change re-applies commit c53655545141 ("drm/amd/display: dsc mst
re-compute pbn for changes on hub").
With an additional check for these older MST devices.

[Why]
Idle optimizations are blocked if there's more than one eDP connector
on the board - blocking S0i3 and IPS2 for static screen.
[How]
Fix the checks to correctly detect number of active eDP.
Also restrict the eDP support to panels that have correct feature
support.

[Why]
This fixes a bug introduced by commit c53655545141 ("drm/amd/display: dsc
mst re-compute pbn for changes on hub").
The change caused light-up issues with a second display that required
DSC on some MST docks.
[How]
Use Virtual DPCD for DSC caps in MST case.
[Limitations]
This change only affects MST DSC devices that follow specifications
additional changes are required to check for old MST DSC devices such as
ones which do not check for Virtual DPCD registers.

Underflow occurs when running Netflix in a 4k144 eDP + 4k60 HDMI FRL

[How]
Enable urgent latency adjustment and match the reference to existing
ASIC that also see increased latency at low FCLK.

During successful probe, igc logs this:
[ 5.133667] igc 0000:01:00.0 (unnamed net_device) (uninitialized): PHC added
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The reason is that igc_ptp_init() is called very early, even before
register_netdev() has been called. So the netdev_info() call works
on a partially uninitialized netdev.
Fix this by calling igc_ptp_init() after register_netdev(), right
after the media autosense check, just as in igb. Add a comment,
just as in igb.

====================
rxrpc: Miscellaneous fixes (part)
Here some miscellaneous fixes for AF_RXRPC:
(1) Fix the congestion control algorithm to start cwnd at 4 and to not cut
ssthresh when the peer cuts its rwind size.
(2) Only transmit a single ACK for all the DATA packets glued together
into a jumbo packet to reduce the number of ACKs being generated.
====================

Signed-off-by: Jakub Kicinski <kuba@kernel.org>
Only generate one ACK packet for all the subpackets in a jumbo packet. If
we would like to generate more than one ACK, we prioritise them base on
their reason code, in the order, highest first:
OutOfSeq > NoSpace > ExceedsWin > Duplicate > Requested > Delay > Idle
For the first four, we reference the lowest offending subpacket; for the
last three, the highest.
This reduces the number of ACKs we end up transmitting to one per UDP
packet transmitted to reduce network loading and packet parsing.

Make the following fixes to the congestion control algorithm:
(1) Don't vary the cwnd starting value by the size of RXRPC_TX_SMSS since
that's currently held constant - set to the size of a jumbo subpacket
payload so that we can create jumbo packets on the fly. The current
code invariably picks 3 as the starting value.
Further, the starting cwnd needs to be an even number because we ack
every other packet, so set it to 4.
(2) Don't cut ssthresh when we see an ACK come from the peer with a
receive window (rwind) less than ssthresh. ssthresh keeps track of
characteristics of the connection whereas rwind may be reduced by the
peer for any reason - and may be reduced to 0.

When creating the topology for the test, three veth pairs are created in
the initial network namespace before being moved to one of the network
namespaces created by the test.
On systems where systemd-udev uses MACAddressPolicy=persistent (default
since systemd version 242), this will result in some net devices having
the same MAC address since they were created with the same name in the
initial network namespace. In turn, this leads to arping / ndisc6
failing since packets are dropped by the bridge's loopback filter.
Fix by creating each net device in the correct network namespace instead
of moving it there from the initial network namespace.

It is possible that the host connected and saw a cm established
event and started sending nvme capsules on the qp, however the
ctrl did not yet see an established event. This is why the
rsp_wait_list exists (for async handling of these cmds, we move
them to a pending list).
Furthermore, it is possible that the ctrl cm times out, resulting
in a connect-error cm event. in this case we hit a bad deref [1]
because in nvmet_rdma_free_rsps we assume that all the responses
are in the free list.
We are freeing the cmds array anyways, so don't even bother to
remove the rsp from the free_list. It is also guaranteed that we
are not racing anything when we are releasing the queue so no
other context accessing this array should be running.

The nsid value is a u32 that comes from nvmet_req_find_ns(). It's
endian data and we're on an error path and both of those raise red
flags. So let's make this safer.
1) Make the buffer large enough for any u32.
2) Remove the unnecessary initialization.
3) Use snprintf() instead of sprintf() for even more safety.
4) The sprintf() function returns the number of bytes printed, not
counting the NUL terminator. It is impossible for the return value to
be <= 0 so delete that.

- run_estimation
- est_cpulist

Currently the ipq806x dwmac driver is almost always used attached to the
CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii".
Some device came up with a special configuration where the PHY is
directly attached to the GMAC port and in those case phy-mode needs to
be set to "rgmii-id" to make the PHY correctly work and receive packets.
Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id"
(or variants) mode is set, the mode is rejected and probe fails.
Add support also for these phy-modes to correctly setup PHYs that requires
delay applied to tx/rx.

Enhance the error reporting mechanism in the switchdev framework to
provide more informative and user-friendly error messages.
Following feedback from users struggling to understand the implications
of error messages like "failed (err=-28) to add object (id=2)", this
update aims to clarify what operation failed and how this might impact
the system or network.
With this change, error messages now include a description of the failed
operation, the specific object involved, and a brief explanation of the
potential impact on the system. This approach helps administrators and
developers better understand the context and severity of errors,
facilitating quicker and more effective troubleshooting.
Example of the improved logging:
[ 70.516446] ksz-switch spi0.0 uplink: Failed to add Port Multicast
Database entry (object id=2) with error: -ENOSPC (-28).
[ 70.516446] Failure in updating the port's Multicast Database could
lead to multicast forwarding issues.
[ 70.516446] Current HW/SW setup lacks sufficient resources.
This comprehensive update includes handling for a range of switchdev
object IDs, ensuring that most operations within the switchdev framework
benefit from clearer error reporting.

When a broadcast AppleTalk packet is received, prefer queuing it on the
socket whose address matches the address of the interface that received
the packet (and is listening on the correct port). Userspace
applications that handle such packets will usually send a response on
the same socket that received the packet; this fix allows the response
to be sent on the correct interface.
If a socket matching the interface's address is not found, an arbitrary
socket listening on the correct port will be used, if any. This matches
the implementation's previous behavior.
Fixes atalkd's responses to network information requests when multiple
network interfaces are configured to use AppleTalk.

Introduce a tracepoint for icmp_send, which can help users to get more
detail information conveniently when icmp abnormal events happen.
1. Giving an usecase example:
=============================
When an application experiences packet loss due to an unreachable UDP
destination port, the kernel will send an exception message through the
icmp_send function. By adding a trace point for icmp_send, developers or
system administrators can obtain detailed information about the UDP
packet loss, including the type, code, source address, destination address,
source port, and destination port. This facilitates the trouble-shooting
of UDP packet loss issues especially for those network-service
applications.
2. Operation Instructions:
==========================
Switch to the tracing directory.
cd /sys/kernel/tracing
Filter for destination port unreachable.
echo "type==3 && code==3" > events/icmp/icmp_send/filter
Enable trace event.
echo 1 > events/icmp/icmp_send/enable
3. Result View:
================

====================
add DCB and DSCP support for KSZ switches
This patch series is aimed at improving support for DCB (Data Center
Bridging) and DSCP (Differentiated Services Code Point) on KSZ switches.
The main goal is to introduce global DSCP and PCP (Priority Code Point)
mapping support, addressing the limitation of KSZ switches not having
per-port DSCP priority mapping. This involves extending the DSA
framework with new callbacks for managing trust settings for global DSCP
and PCP maps. Additionally, we introduce IEEE 802.1q helpers for default
configurations, benefiting other drivers too.
Change logs are in separate patches.
Compared to v6 this series includes some new patches for DSCP global
mapping support and QoS selftest script for KSZ9477 switches.

it is possible to disable PCP prios.
- DSCP classification is not working on Port 2.
