ds->user_mii_bus cleanup (part 1)

There are some drivers which assign ds->user_mii_bus when they
don't really need its specific functionality, aka non-OF based
dsa_user_phy_connect(). There was some confusion regarding the
fact that yes, this is why ds->user_mii_bus really exists, so
I've started a cleanup series which aims to eliminate the usage
of ds->user_mii_bus from drivers when there is nothing to gain
from it.

Today's drivers are lantiq_gswip, qca8k and bcm_sf2. The work is
not done here, but a "part 2" may or may not come, depending on
other priorities.

All patches were only compile-tested.

There used to be a of_node_put(priv->master_mii_dn) call in
bcm_sf2_mdio_unregister(), which was accidentally deleted in commit
6ca80638 ("net: dsa: Use conduit and user terms").

But it's not needed - we don't need to hold a reference on the
"brcm,unimac-mdio" OF node for that long, since we don't do anything
with it. We can release it as soon as we finish bcm_sf2_mdio_register().

Also reduce "if (err && dn)" to just "if (err)". We know "dn", aka the
former priv->master_mii_dn, is non-NULL. Otherwise, of_mdio_find_bus(dn)
would not have been able to find the bus behind "brcm,unimac-mdio".

The bcm_sf2 driver does something strange. Instead of calling
of_mdiobus_register() with an OF node argument, it manually assigns the
bus->dev->of_node and then calls the non-OF mdiobus_register(). This
circumvents some code from __of_mdiobus_register() from running, which
sets the auto-scan mask, parses some device tree properties, etc.

I'm going to go out on a limb and say that the OF node isn't, in fact,
needed at all, and can be removed. The MDIO diversion as initially
implemented in commit 461cd1b0 ("net: dsa: bcm_sf2: Register our
slave MDIO bus") looked quite different than it is now, after commit
771089c2 ("net: dsa: bcm_sf2: Ensure that MDIO diversion is used").
Initially, it made sense, as bcm_sf2 was registering another set of
driver ops for the "brcm,unimac-mdio" OF node. But now, it deletes all
phandles, which makes "phy-handle"s unable to find PHYs, which means
that it always goes through the OF-unaware dsa_user_phy_connect().

To simplify reasoning about why the DSA framework provides the
ds->user_mii_bus functionality, drivers should only use it if they
need to. The qca8k driver appears to also use it simply as storage
for a pointer, which is not a good enough reason to make the core
much more difficult to follow.

ds->user_mii_bus is useful for only 2 cases:

1. The driver probes on platform_data (no OF)
2. The driver probes on OF, but there is no OF node for the MDIO bus.

It is unclear if case (1) is supported with qca8k. It might not be:
the driver might crash when of_device_get_match_data() returns NULL
and then it dereferences priv->info without NULL checking.

Anyway, let us limit the ds->user_mii_bus usage only to the above cases,
and not assign it when an OF node is present.

The bus->phy_mask assignment follows along with the movement, because
__of_mdiobus_register() overwrites this bus field anyway. The value set
by the driver only matters for the non-OF code path.

Currently the driver calls the non-OF devm_mdiobus_register() rather
than devm_of_mdiobus_register() for this case, but it seems to rather
be a confusing coincidence, and not a real use case that needs to be
supported.

If the device tree says status = "disabled" for the MDIO bus, we
shouldn't need an MDIO bus at all. Instead, just exit as early as
possible and do not call any MDIO API.

of_get_child_by_name() gives us an OF node with an elevated refcount,
which should be dropped when we're done with it. This is so that,
if (of_node_check_flag(node, OF_DYNAMIC)) is true, the node's memory can
eventually be freed.

There are 2 distinct paths to be considered in qca8k_mdio_register():

- devm_of_mdiobus_register() succeeds: since commit 3b73a7b8 ("net:
  mdio_bus: add refcounting for fwnodes to mdiobus"), the MDIO core
  treats this well.

- devm_of_mdiobus_register() or anything up to that point fails: it is
  the duty of the qca8k driver to release the OF node.

This change addresses the second case by making sure that the OF node
reference is not leaked.

The "mdio" node may be NULL, but of_node_put(NULL) is safe.

This driver does not need any of the functionalities that make
ds->user_mii_bus special. Those use cases are listed here:
https://lore.kernel.org/netdev/20231221174746.hylsmr3f7g5byrsi@skbuf/

It just makes use of ds->user_mii_bus only as storage for its own MDIO
bus, which otherwise has no connection to the framework. This is because:

- the gswip driver only probes on OF: it fails if of_device_get_match_data()
  returns NULL

- when the child OF node of the MDIO bus is absent, no MDIO bus is
  registered at all, not even by the DSA framework. In order for that to
  have happened, the gswip driver would have needed to provide
  ->phy_read() and ->phy_write() in struct dsa_switch_ops, which it does
  not.

We can break the connection between the gswip driver and the DSA
framework and still preserve the same functionality.

Since commit 3b73a7b8 ("net: mdio_bus: add refcounting for fwnodes
to mdiobus"), MDIO buses take ownership of the OF node handled to them,
and release it on their own. The gswip driver no longer needs to do
this.

Combine that with devres, and we no longer need to keep track of
anything for teardown purposes.

Inserting the device to block xarray in qdisc_create() is not suitable
place to do this. As it requires use of tcf_block() callback, it causes
multiple issues. It is called for all qdisc types, which is incorrect.

So, instead, move it to more suitable place, which is tcf_block_get_ext()
and make sure it is only done for qdiscs that use block infrastructure
and also only for blocks which are shared.

Symmetrically, alter the cleanup path, move the xarray entry removal

Commit 688eb819 ("x86/csum: Improve performance of `csum_partial`")
ended up improving the code generation for the IP csum calculations, and
in particular special-casing the 40-byte case that is a hot case for
IPv6 headers.

It then had _another_ special case for the 64-byte unrolled loop, which
did two chains of 32-byte blocks, which allows modern CPU's to improve
performance by doing the chains in parallel thanks to renaming the carry
flag.

This just unifies the special cases and combines them into just one
single helper the 40-byte csum case, and replaces the 64-byte case by a
80-byte case that just does that single helper twice.  It avoids having
all these different versions of inline assembly, and actually improved
performance further in my tests.

There was never anything magical about the 64-byte unrolled case, even
though it happens to be a common size (and typically is the cacheline
size).

The special case for odd aligned buffers is unnecessary and mostly
just adds overhead. Aligned buffers is the expectations, and even for
unaligned buffer, the only case that was helped is if the buffer was
1-byte from word aligned which is ~1/7 of the cases. Overall it seems
highly unlikely to be worth to extra branch.

It was left in the previous perf improvement patch because I was
erroneously comparing the exact output of `csum_partial(...)`, but
really we only need `csum_fold(csum_partial(...))` to match so its
safe to remove.

All csum kunit tests pass.

User won't care about inproper hash options in the TCP header if they
don't use neither TCP-AO nor TCP-MD5. Yet, those logs can add up in
syslog, while not being a real concern to the host admin:
> kernel: TCP: TCP segment has incorrect auth options set for XX.20.239.12.54681->XX.XX.90.103.80 [S]

Keep silent and avoid logging when there aren't any keys in the system.

Side-note: I also defined static_branch_tcp_*() helpers to avoid more
ifdeffery, going to remove more ifdeffery further with their help.

This reverts commit b28ff7a7.

The commit introduced P2SB device scan and resource cache during the
boot process to avoid deadlock. But it caused detection failure of
IDE controllers on old systems [1]. The IDE controllers on old systems
and P2SB devices on newer systems have same PCI DEVFN. It is suspected
the confusion between those two is the failure cause. Revert the change
at this moment until the proper solution gets ready.

Luiz Angelo Daros de Luca reports that the MDIO bus code maintains a
reference to the DT node, but does not hold a refcount on the node.

The simple solution to this is to add the necessary refcounting into
the MDIO bus code for all users, ensuring that on registration, the
refcount is incremented, and only dropped when the MDIO bus is
released.

Do this for fwnodes, so we not only fix this for DT, but also other
types of firmware nodes as well.

CSR.OPS bits specify the current operating mode and (according to
documentation) they are updated by HW when the operating mode change
request is processed. To comply with this check CSR.OPS before proceeding.

Commit introduces ravb_set_opmode() that does all the necessities for
setting the operating mode (set CCC.OPC (and CCC.GAC, CCC.CSEL, if any) and
wait for CSR.OPS) and call it where needed. This should comply with all the
HW manuals requirements as different manual variants specify that different
modes need to be checked in CSR.OPS when setting CCC.OPC.

If gPTP active in config mode is supported and it needs to be enabled, the
CCC.GAC and CCC.CSEL needs to be configured along with CCC.OPC in the same
write access. For this, ravb_set_opmode() allows passing GAC and CSEL as
part of opmode and the function updates accordingly CCC register.
