58ba426388 net/packet: add PACKET_FANOUT_FLAG_IGNORE_OUTGOING
Extend packet socket option PACKET_IGNORE_OUTGOING to fanout groups.

The socket option sets ptype.ignore_outgoing, which makes
dev_queue_xmit_nit skip the socket.

When the socket joins a fanout group, the option is not reflected in
the struct ptype of the group. dev_queue_xmit_nit only tests the
fanout ptype, so the flag is ignored once a socket joins a
fanout group.

Inheriting the option from a socket would change established behavior.
Different sockets in the group can set different flags, and can also
change them at runtime.

Testing in packet_rcv_fanout defeats the purpose of the original
patch, which is to avoid skb_clone in dev_queue_xmit_nit (esp. for
MSG_ZEROCOPY packets).

Instead, introduce a new fanout group flag with the same behavior.

Tested with https://github.com/wdebruij/kerneltools/blob/master/tests/test_psock_fanout_ignore_outgoing.c

a2c65a9d05 net: dsa: fall back to default tagger if we can't load the one from DT
DSA tagging protocol drivers can be changed at runtime through sysfs and
at probe time through the device tree (support for the latter was added
later).

When changing through sysfs, it is assumed that the module for the new
tagging protocol was already loaded into the kernel (in fact this is
only a concern for Ocelot/Felix switches, where we have tag_ocelot.ko
and tag_ocelot_8021q.ko; for every other switch, the default and
alternative protocols are compiled within the same .ko, so there is
nothing for the user to load).

The kernel cannot currently call request_module(), because it has no way
of constructing the modalias name of the tagging protocol driver
("dsa_tag-%d", where the number is one of DSA_TAG_PROTO_*_VALUE).
The device tree only contains the string name of the tagging protocol
("ocelot-8021q"), and the only mapping between the string and the
DSA_TAG_PROTO_OCELOT_8021Q_VALUE is present in tag_ocelot_8021q.ko.
So this is a chicken-and-egg situation and dsa_core.ko has nothing based
on which it can automatically request the insertion of the module.

As a consequence, if CONFIG_NET_DSA_TAG_OCELOT_8021Q is built as module,
the switch will forever defer probing.

The long-term solution is to make DSA call request_module() somehow,
but that probably needs some refactoring.

What we can do to keep operating with existing device tree blobs is to
cancel the attempt to change the tagging protocol with the one specified
there, and to remain operating with the default one. Depending on the
situation, the default protocol might still allow some functionality
(in the case of ocelot, it does), and it's better to have that than to
fail to probe.

Fixes: deff710703 ("net: dsa: Allow default tag protocol to be overridden from DT")

637639cbfe ice: Add additional CSR registers to ETHTOOL_GREGS
In the event of a Tx hang it can be useful to read a variety of hardware
registers to capture some state about why the transmit queue got stuck.

Extend the ETHTOOL_GREGS dump provided by the ice driver with several CSR
registers that provide such relevant information regarding the hardware Tx
state. This enables capturing relevant data to enable debugging such a Tx
hang.

Russell King says:

====================
net: mtk_eth_soc: improve PCS implementation

As a result of invesigations from Frank Wunderlich, we know a lot more
about the Mediatek "SGMII" PCS block, and can implement the PCS support
correctly. This series achieves that, and Frank has tested the final
result and reports that it works for him. The series could do with
further testing by others, but I suspect that is unlikely to happen
until it is merged based on past performances with this driver.

Briefly, the patches in order:

1. Add a new helper to get the link timer duration in nanoseconds
2. Add definitions for the newly discovered registers and updates to
   bit definitions, including bitmasks for the BMCR, BMSR and two
   advertisement registers.
3. Remove unnecessary/unused error handling (functions always returning
   zero.)
4. Adding the missing pcs_get_state() implementation.
5. Converting the code to use regmap_update_bits() rather than
   open-coding read-modify-write sequences.
6. Adding out-of-band speed and duplex forcing for all non-inband modes
   not just the 802.3z link modes the code currently does.
7. Moving the release of the PHY power down to the main pcs_config()
   function.
8. Moving the interface speed selection to the main pcs_config()
   function.
9. Adding advertisement programming.
10. Adding correct link timer programming using the new helper in the
    first patch.
11. Adding support for 802.3z negotiation.

There is one remaining issue - when configuring the PCS for in-band,
for some reason the AN restart bit is always set. This should not be
necessary, but requires further investigation with the hardware to
find out whether it is really necessary. I suspect this was a work
around for a previous poor implementation.

First set of patches v6.2. mac80211 refactoring continues for Wi-Fi 7.
 All mac80211 driver are now converted to use internal TX queues, this
 might cause some regressions so we wanted to do this early in the
 cycle.
 
 Note: wireless tree was merged[1] to wireless-next to avoid some
 conflicts with mac80211 patches between the trees. Unfortunately there
 are still two smaller conflicts in net/mac80211/util.c which Stephen
 also reported[2]. In the first conflict initialise scratch_len to
 "params->scratch_len ?: 3 * params->len" (note number 3, not 2!) and
 in the second conflict take the version which uses elems->scratch_pos.

For NAND modules Toradex does not provide any device-tree overlays. But

Toradex does provide device-tree overlays to enable certain evaluation
hardware. Keep the buses disabled by default to be enabled again with
overlays.

For customers including this device-tree this has also the advantage
that the hardware we want by default running does not automatically
enable signals on their end.

After we support HAVE_ARCH_HUGE_VMAP, we can now enable
HAVE_ARCH_HUGE_VMALLOC too. This feature has been used in kvmalloc and
alloc_large_system_hash for now. This feature can be disabled by kernel
parameters "nohugevmalloc".
