====================
Hirschmann Hellcreek DSA driver

this series adds a DSA driver for the Hirschmann Hellcreek TSN switch
IP. Characteristics of that IP:

 * Full duplex Ethernet interface at 100/1000 Mbps on three ports
 * IEEE 802.1Q-compliant Ethernet Switch
 * IEEE 802.1Qbv Time-Aware scheduling support
 * IEEE 1588 and IEEE 802.1AS support

That IP is used e.g. in

 https://www.arrow.com/en/campaigns/arrow-kairos

Due to the hardware setup the switch driver is implemented using DSA. A special
tagging protocol is leveraged. Furthermore, this driver supports PTP and
hardware timestamping.

This work is part of the AccessTSN project: https://www.accesstsn.com/

7d9ee2e8ff net: dsa: hellcreek: Add PTP status LEDs
The switch has two controllable I/Os which are usually connected to LEDs. This
is useful to immediately visually see the PTP status.

These provide two signals:

 * is_gm

   This LED can be activated if the current device is the grand master in that
   PTP domain.

 * sync_good

   This LED can be activated if the current device is in sync with the network
   time.

Expose these via the LED framework to be controlled via user space
e.g. linuxptp.

f0d4ba9eff net: dsa: hellcreek: Add support for hardware timestamping
The switch has the ability to take hardware generated time stamps per port for
PTPv2 event messages in Rx and Tx direction. That is useful for achieving needed
time synchronization precision for TSN devices/switches. So add support for it.

There are two directions:

 * RX

   The switch has a single register per port to capture a timestamp. That
   mechanism is not used due to correlation problems. If the software processing
   is too slow and a PTPv2 event message is received before the previous one has
   been processed, false timestamps will be captured. Therefore, the switch can
   do "inline" timestamping which means it can insert the nanoseconds part of
   the timestamp directly into the PTPv2 event message. The reserved field (4
   bytes) is leveraged for that. This might not be in accordance with (older)
   PTP standards, but is the only way to get reliable results.

 * TX

   In Tx direction there is no correlation problem, because the software and the
   driver has to ensure that only one event message is "on the fly". However,
   the switch provides also a mechanism to check whether a timestamp is
   lost. That can only happen when a timestamp is read and at this point another
   message is timestamped. So, that lost bit is checked just in case to indicate
   to the user that the driver or the software is somewhat buggy.

ddd56dfe52 net: dsa: hellcreek: Add PTP clock support
The switch has internal PTP hardware clocks. Add support for it. There are three
clocks:

 * Synchronized
 * Syntonized
 * Free running

Currently the synchronized clock is exported to user space which is a good
default for the beginning. The free running clock might be exported later
e.g. for implementing 802.1AS-2011/2020 Time Aware Bridges (TAB). The switch
also supports cross time stamping for that purpose.

The implementation adds support setting/getting the time as well as offset and
frequency adjustments. However, the clock only holds a partial timeofday
timestamp. This is why we track the seconds completely in software (see overflow
work and last_ts).

Furthermore, add the PTP multicast addresses into the FDB to forward that
packages only to the CPU port where they are processed by a PTP program.

e358bef7c3 net: dsa: Give drivers the chance to veto certain upper devices
Some switches rely on unique pvids to ensure port separation in
standalone mode, because they don't have a port forwarding matrix
configurable in hardware. So, setups like a group of 2 uppers with the
same VLAN, swp0.100 and swp1.100, will cause traffic tagged with VLAN
100 to be autonomously forwarded between these switch ports, in spite
of there being no bridge between swp0 and swp1.

These drivers need to prevent this from happening. They need to have
VLAN filtering enabled in standalone mode (so they'll drop frames tagged
with unknown VLANs) and they can only accept an 8021q upper on a port as
long as it isn't installed on any other port too. So give them the
chance to veto bad user requests.

01ef09caad net: dsa: Add tag handling for Hirschmann Hellcreek switches
The Hirschmann Hellcreek TSN switches have a special tagging protocol for frames
exchanged between the CPU port and the master interface. The format is a one
byte trailer indicating the destination or origin port.

It's quite similar to the Micrel KSZ tagging. That's why the implementation is
based on that code.

108aa50365 arm64: kexec_file: try more regions if loading segments fails
It's possible that the first region picked for the new kernel will make
it impossible to fit the other segments in the required 32GB window,
especially if we have a very large initrd.

Instead of giving up, we can keep testing other regions for the kernel
until we find one that works.

5144368571 net: mlx5: Replace in_irq() usage
mlx5_eq_async_int() uses in_irq() to decide whether eq::lock needs to be
acquired and released with spin_[un]lock() or the irq saving/restoring
variants.

The usage of in_*() in drivers is phased out and Linus clearly requested
that code which changes behaviour depending on context should either be
seperated or the context be conveyed in an argument passed by the caller,
which usually knows the context.

mlx5_eq_async_int() knows the context via the action argument already so
using it for the lock variant decision is a straight forward replacement
for in_irq().

579524c6ea net/mlx5e: Validate stop_room size upon user input
Stop room is a space that may be taken by WQEs in the SQ during a packet
transmit. It is used to check if next packet has enough room in the SQ.
Stop room guarantees this packet can be served and if not, the queue is
stopped, so no more packets are passed to the driver until it's ready.

Currently, stop_room size is calculated and validated upon tx queues
allocation. This makes it impossible to know if user provided valid
input for certain parameters when interface is down.

Instead, store stop_room in mlx5e_sq_param and create
mlx5e_validate_params(), to validate its fields upon user input even
when the interface is down.

ae23b55cc5 Merge branch 'mptcp-miscellaneous-mptcp-fixes'
Mat Martineau says:

====================
mptcp: Miscellaneous MPTCP fixes

This is a collection of small fixup and minor enhancement patches that
have accumulated in the MPTCP tree while net-next was closed. These are
prerequisites for larger changes we have queued up.

Patch 1 refines receive buffer autotuning.

Patches 2 and 4 are some minor locking and refactoring changes.

Patch 3 improves GRO and RX coalescing with MPTCP skbs.

Patches 5-7 add a sysctl for tuning ADD_ADDR retransmission timeout,
corresponding test code, and documentation.

v2: Add sysctl documentation and fix signoff tags.

8d014eaa92 selftests: mptcp: add ADD_ADDR timeout test case
This patch added the test case for retransmitting ADD_ADDR when timeout
occurs. It set NS1's add_addr_timeout to 1 second, and drop NS2's ADD_ADDR
echo packets.

Here we need to slow down the transfer process of all data to let the
ADD_ADDR suboptions can be retransmitted three times. So we added a new
parameter "speed" for do_transfer, it can be set with fast or slow.

We also added three new optional parameters for run_tests, and dropped
run_remove_tests function.

Since we added the netfilter rules in this test case, we need to update
the "config" file.

95ed690ebc mptcp: split mptcp_clean_una function
mptcp_clean_una() will wake writers in case memory could be reclaimed.
When called from mptcp_sendmsg the wakeup code isn't needed.

Move the wakeup to a new helper and then use that from the mptcp worker.

5a369ca643 tcp: propagate MPTCP skb extensions on xmit splits
When the TCP stack splits a packet on the write queue, the tail
half currently lose the associated skb extensions, and will not
carry the DSM on the wire.

The above does not cause functional problems and is allowed by
the RFC, but interact badly with GRO and RX coalescing, as possible
candidates for aggregation will carry different TCP options.

This change tries to improve the MPTCP behavior, propagating the
skb extensions on split.

Additionally, we must prevent the MPTCP stack from updating the
mapping after the split occur: that will both violate the RFC and
fool the reader.

13c7ba0c84 mptcp: adjust mptcp receive buffer limit if subflow has larger one
In addition to tcp autotuning during read, it may also increase the
receive buffer in tcp_clamp_window().

In this case, mptcp should adjust its receive buffer size as well so
it can move all pending skbs from the subflow socket to the mptcp socket.

At this time, TCP can have more skbs ready for processing than what the
mptcp receive buffer size allows.

In the mptcp case, the receive window announced is based on the free
space of the mptcp parent socket instead of the individual subflows.

Following the subflow allows mptcp to grow its receive buffer.

This is especially noticeable for loopback traffic where two skbs are
enough to fill the initial receive window.

In mptcp_data_ready() we do not hold the mptcp socket lock, so modifying
mptcp_sk->sk_rcvbuf is racy.  Do it when moving skbs from subflow to
mptcp socket, both sockets are locked in this case.

2aaf09a0e7 r8169: work around short packet hw bug on RTL8125
Network problems with RTL8125B have been reported [0] and with help
from Realtek it turned out that this chip version has a hw problem
with short packets (similar to RTL8168evl). Having said that activate
the same workaround as for RTL8168evl.
Realtek suggested to activate the workaround for RTL8125A too, even
though they're not 100% sure yet which RTL8125 versions are affected.
