Recent discussions show that skb_reset_mac_len() should be more careful.
We expect the MAC header being set.
If not, clear skb->mac_len and fire a warning for CONFIG_DEBUG_NET=y builds.
If after investigations we find that not having a MAC header was okay,
we can remove the warning.

This addresses the infamous unregister_netdevice splat in net selftests;
the actual fix is carried by the first patch, while the 2nd one

hiding the problem.
Targeting net-next as the issue is quite old and I feel a little lost

fan speed
Fix for Thinkpad's with ECFW showing incorrect fan speed. Some models use
decimal instead of hexadecimal for the speed stored in the EC registers.
For example the rpm register will have 0x4200 instead of 0x1068, here
the actual RPM is "4200" in decimal.
Add a quirk to handle this.

mptcp_get_available_schedulers() needs to iterate over the schedulers'
list only to read the names: it doesn't modify anything there.
In this case, it is enough to hold the RCU read lock, no need to combine
this with the associated spin lock as it was done since its introduction
in commit 73c900aa3660 ("mptcp: add net.mptcp.available_schedulers").

The local address entries on userspace_pm_local_addr_list are allocated

During the switch to YNL, the command to list all endpoints has been
accidentally restricted to users with admin permissions.
It looks like there are no reasons to have this restriction which makes
it harder for a user to quickly check if the endpoint list has been
correctly populated by an automated tool. Best to go back to the
previous behaviour then.
mptcp_pm_gen.c has been modified using ynl-gen-c.py:
$ ./tools/net/ynl/ynl-gen-c.py --mode kernel \
--spec Documentation/netlink/specs/mptcp_pm.yaml --source \
-o net/mptcp/mptcp_pm_gen.c

Add the dwmac driver support for T-HEAD TH1520 SoC
This series adds support for dwmac gigabit ethernet in the T-Head TH1520
RISC-V SoC used on boards like BeagleV Ahead and the LicheePi 4A.
The gigabit ethernet on these boards does need pinctrl support to mux
the necessary pads. The pinctrl-th1520 driver, pinctrl binding, and
related dts patches are in linux-next. However, they are not yet in
net-next/main.
Therefore, I am dropping the dts patch for v5 as it will not build on
net-next/main due to the lack of the padctrl0_apsys pin controller node
in next-next/main version th1520.dtsi. It does exist in linux-next [1]
and the two patches in this series allow the ethernet ports to work
correctly on the LPi4A and Ahead when applied to linux-next.
The dwmac-thead driver in this series does not need the pinctrl-th1520
driver to build. Nor does the thead,th1520-gmac.yaml binding need the
pinctrl binding to pass the schema check.

DP83848 datasheet (section 4.7.2) indicates that the reset pin should be
toggled after the clocks are running. Add the PHY_RST_AFTER_CLK_EN to
make sure that this indication is respected.
In my experience not having this flag enabled would lead to, on some
boots, the wrong MII mode being selected if the PHY was initialized on
the bootloader and was receiving data during Linux boot.

Clearing the secpath for internal ports will cause packet drops when
ipsec offload or early SW ipsec decrypt are used. Systems that rely
on these will not be able to actually pass traffic via openvswitch.
There is still an open issue for a flow miss packet - this is because
we drop the extensions during upcall and there is no facility to
restore such data (and it is non-trivial to add such functionality
to the upcall interface). That means that when a flow miss occurs,
there will still be packet drops. With this patch, when a flow is
found then traffic which has an associated xfrm extension will
properly flow.

====================
A pile of sfc deadcode
This is a collection of deadcode removal in the sfc
drivers; the split is vaguely where I found them in
the tree, with some left over.
This has been build tested and booted on an x86 VM,
but I fon't have the hardware to test; however
it's all full function removal.

efx_ticks_to_usecs(), efx_reconfigure_port(), efx_ptp_get_mode(), and
efx_tx_get_copy_buffer_limited() are unused.
They seem to be partially due to the later splits to Siena, but
some seem unused for longer.
Remove them.

efx_mcdi_flush_rxqs(), efx_mcdi_rpc_async_quiet(),
efx_mcdi_rpc_finish_quiet(), and efx_mcdi_wol_filter_get_magic()

I think these are fall out from the split into Siena

commit 4d49e5cd4b09 ("sfc/siena: Rename functions in mcdi headers to avoid
conflicts with sfc")
and

We can see high contention on ptp_lock while doing RX timestamping
on high packet rates over several queues. Spinlock is not effecient
to protect timecounter for RX timestamps when reads are the most
usual operations and writes are only occasional. It's better to use
seqlock in such cases.

This hardware can provide only 48 bits of cycle counter. We can leave
only 24 bits in the cache to extend RX timestamps from 32 bits to 48
bits. Lower 8 bits of the cached value will be used to check for
roll-over while extending to full 48 bits.
This change makes cache writes atomic even on 32 bit platforms and we
can simply use READ_ONCE()/WRITE_ONCE() pair and remove spinlock. The
configuration structure will be also reduced by 4 bytes.

Recently, the net/lib.sh file has been modified to include defer.sh from
net/lib/sh/ directory. The Makefile from net/lib has been modified
accordingly, but not the ones from the sub-targets using net/lib.sh.
Because of that, the new file is not installed as expected when
installing the Forwarding, MPTCP, and Netfilter targets, e.g.
# make -C tools/testing/selftests TARGETS=net/mptcp install \
INSTALL_PATH=/tmp/kself
# cd /tmp/kself/
# ./run_kselftest.sh -c net/mptcp
TAP version 13
1..7
# timeout set to 1800
# selftests: net/mptcp: mptcp_connect.sh
# ./../lib.sh: line 5: /tmp/kself/net/lib/sh/defer.sh: No such file
or directory
# (...)
This can be fixed simply by adding all the .sh files from net/lib/sh
directory to the TEST_INCLUDES variable in the different Makefile's.

Update of stateful object triggers:
WARNING: suspicious RCU usage
net/netfilter/nf_tables_api.c:7759 RCU-list traversed in non-reader section!!
other info that might help us debug this:
rcu_scheduler_active = 2, debug_locks = 1
1 lock held by nft/3060:
#0: ffff88810f0578c8 (&nft_net->commit_mutex){+.+.}-{4:4}, [..]
... but this list is not protected by the transaction mutex but the
nfnl nftables subsystem mutex.
Switch to nft_obj_type_get which will acquire rcu read lock,
bump refcount, and returns the result.
v3: Dan Carpenter points out nft_obj_type_get returns error pointer, not
NULL, on error.
