During virtnet_probe, default rss configuration is initialized, but was
not committed to the device. This patch fix this by sending rss command
after device ready in virtnet_probe. Otherwise, the actual rss
configuration used by device can be different with that read by user
from driver, which may confuse the user.
If the command committing fails, driver rss will be disabled.

When reading/writing virtio_net_ctrl_rss, we get the indirection table
size from vi->rss_indir_table_size, which is initialized in
virtnet_probe(). However, the actual size of indirection_table was set
as VIRTIO_NET_RSS_MAX_TABLE_LEN=128. This collision may cause issues if
the vi->rss_indir_table_size exceeds 128.
This patch instead uses dynamic indirection table, allocated with
vi->rss after vi->rss_indir_table_size initialized. And free it in
virtnet_remove().
In virtnet_commit_rss_command(), sgs for rss is initialized differently
with hash_report. So indirection_table is not used if !vi->has_rss, and
then we don't need to alloc indirection_table for hash_report only uses.

8c873e219970 ("netfilter: core: free hooks with call_rcu") removed
synchronize_net() call when unregistering basechain hook, however,
net_device removal event handler for the NFPROTO_NETDEV was not updated
to wait for RCU grace period.
Note that 835b803377f5 ("netfilter: nf_tables_netdev: unregister hooks
on net_device removal") does not remove basechain rules on device
removal, I was hinted to remove rules on net_device removal later, see
5ebe0b0eec9d ("netfilter: nf_tables: destroy basechain and rules on
netdevice removal").
Although NETDEV_UNREGISTER event is guaranteed to be handled after
synchronize_net() call, this path needs to wait for rcu grace period via
rcu callback to release basechain hooks if netns is alive because an
ongoing netlink dump could be in progress (sockets hold a reference on
the netns).
Note that nf_tables_pre_exit_net() unregisters and releases basechain
hooks but it is possible to see NETDEV_UNREGISTER at a later stage in
the netns exit path, eg. veth peer device in another netns:
cleanup_net()
default_device_exit_batch()
unregister_netdevice_many_notify()
notifier_call_chain()
nf_tables_netdev_event()
__nft_release_basechain()
In this particular case, same rule of thumb applies: if netns is alive,
then wait for rcu grace period because netlink dump in the other netns
could be in progress. Otherwise, if the other netns is going away then
no netlink dump can be in progress and basechain hooks can be released
inmediately.
While at it, turn WARN_ON() into WARN_ON_ONCE() for the basechain
validation, which should not ever happen.

Add support to redirect host-to-BMC traffic by writing MACDA entries
from the RPC (RX Parser and Classifier) to TCE-TCAM. The TCE TCAM is a
small L2 destination TCAM which is placed at the end of the TX path (TCE).
Unlike other NICs, where BMC diversion is typically handled by firmware,
for fbnic, firmware does not touch anything related to the host; hence,
the host uses TCE TCAM to divert BMC traffic.
Currently, we lack metadata to track where addresses have been written
in the TCAM, except for the last entry written. To address this issue,
we start at the opposite end of the table in each pass, so that adding
or deleting entries does not affect the availability of all entries,
assuming there is no significant reordering of entries.

Add a 20-byte field ats to struct nfc_target and expose it as
NFC_ATTR_TARGET_ATS via the netlink interface. The payload contains
'historical bytes' that help to distinguish cards from one another.
The information is commonly used to assemble an emulated ATR similar
to that reported by smart cards with contacts.
Add a 20-byte field target_ats to struct nci_dev to hold the payload
obtained in nci_rf_intf_activated_ntf_packet() and copy it to over to
nfc_target.ats in nci_activate_target(). The approach is similar
to the handling of 'general bytes' within ATR_RES.
Replace the hard-coded size of rats_res within struct
activation_params_nfca_poll_iso_dep by the equal constant NFC_ATS_MAXSIZE
now defined in nfc.h
Within NCI, the information corresponds to the 'RATS Response' activation
parameter that omits the initial length byte TL. This loses no
information and is consistent with our handling of SENSB_RES that
also drops the first (constant) byte.
Tested with nxp_nci_i2c on a few type A targets including an
ICAO 9303 compliant passport.
I refrain from the corresponding change to digital_in_recv_ats()
to have the few drivers based on digital.h fill nfc_target.ats,
as I have no way to test it. That class of drivers appear not to set
NFC_ATTR_TARGET_SENSB_RES either. Consider a separate patch to propagate
(all) the parameters.

Commit a23aa0404218 ("net: stmmac: ethtool: Fixed calltrace caused by
unbalanced disable_irq_wake calls") introduced checks to prevent
unbalanced enable and disable IRQ wake calls. However it only
initialized the auxiliary variable on one of the paths,
stmmac_request_irq_multi_msi(), missing the other,
stmmac_request_irq_single().
Add the same initialization on stmmac_request_irq_single() to prevent
"Unbalanced IRQ <x> wake disable" warnings from being printed the first
time disable_irq_wake() is called on platforms that run on that code
path.

The scope of the TX skb is wider than just mse102x_tx_frame_spi(),
so in case the TX skb room needs to be expanded, we should free the
the temporary skb instead of the original skb. Otherwise the original
TX skb pointer would be freed again in mse102x_tx_work(), which leads
to crashes:

bnxt_en: ethtool: Improve wildcard l4proto on ip4/ip6 ntuple rules
This patchset improves wildcarding over l4proto on ip4 and ip6 nutple
rules. Previous support required setting l4proto explicitly to 0xFF if
you wanted wildcard, which ethtool (naturally) did not do. For example,
this command would fail with -EOPNOSUPP:
ethtool -N eth0 flow-type ip6 dst-ip $IP6 context 1
After this patchset, only TCP, UDP, ICMP, and unset will be supported
for l4proto.

Previously, trying to insert an ip4/ip6 ntuple rule with an unset
l4proto would get rejected with -EOPNOTSUPP. For example, the following
would fail:
ethtool -N eth0 flow-type ip6 dst-ip $IP6 context 1
The reason was that all the l4proto validation was being run despite the
l4proto mask being set to 0x0. Fix by respecting the mask on l4proto and
treating a mask of 0x0 as wildcard l4proto.

Commit 9ba0e56199e3 ("bnxt_en: Enhance ethtool ntuple support for ip
flows besides TCP/UDP") added support for ip4/ip6 ntuple rules.
However, if you wanted to wildcard over l4proto, you had to provide
0xFF.
The choice of 0xFF is non-standard and non-intuitive. Delete support for
it in this commit. Next commit we will introduce a cleaner way to
wildcard l4proto.

If we remove modes from EEE advertisement and disable / re-enable EEE,

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").

mptcp: pm: fix wrong perm and sock kfree
Two small fixes related to the MPTCP path-manager:
- Patch 1: remove an accidental restriction to admin users to list MPTCP
endpoints. A regression from v6.7.
- Patch 2: correctly use sock_kfree_s() instead of kfree() in the
userspace PM. A fix for another fix introduced in v6.4 and
backportable up to v5.19.

The local address entries on userspace_pm_local_addr_list are allocated
by sock_kmalloc().
It's then required to use sock_kfree_s() instead of kfree() to free
these entries in order to adjust the allocated size on the sk side.

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
The header file doesn't need to be regenerated.

====================
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.
