Either the AP or modem loads GSI firmware. If the modem-init
property is present, the modem loads it. Otherwise, the AP loads
it, and in that case the memory-region property must be defined.
Currently this requirement is expressed as one or the other of the
modem-init or the memory-region property being required. But it's
harmless for the memory-region to be present if the modem is loading
firmware (it'll just be ignored).
Restate the requirement so that the memory-region property is
required only if modem-init is not present.

Commit d8604b209e9b3 ("dt-bindings: net: qcom,ipa: add firmware-name
property") added a requirement for a "firmware-name" property that
is more restrictive than necessary.
If the AP loads GSI firmware, the name of the firmware file to use
may optionally be provided via a "firmware-name" property. If the
*modem* loads GSI firmware, "firmware-name" doesn't need to be
supplied--but it's harmless to do so (it will simply be ignored).
Remove the unnecessary restriction, and allow "firware-name" to be
supplied even if it's not needed.

So while these weren't regression fixes originally, they are now. It's
not introducing new beahavior, but simply extending the existing new
Devicetree model, to cover remaining platforms:

hardware spinlock on some older platforms to follow the style of
the newer ones where the DeviceTree representation does not rely on

Add packet traps for 802.1X operation. The "eapol" control trap is used
to trap EAPOL packets and is required for the correct operation of the
control plane. The "locked_port" drop trap can be enabled to gain
visibility into packets that were dropped by the device due to the
locked bridge port check.

The previous attempt to augment carrier_down (see Link)
was not met with much enthusiasm so let's do the simple
thing of exposing what some devices already maintain.
Add a common ethtool statistic for link going down.
Currently users have to maintain per-driver mapping
to extract the right stat from the vendor-specific ethtool -S
stats. carrier_down does not fit the bill because it counts
a lot of software related false positives.
Add the statistic to the extended link state API to steer
vendors towards implementing all of it.
Implement for bnxt and all Linux-controlled PHYs. mlx5 and (possibly)
enic also have a counter for this but I leave the implementation
to their maintainers.

The kernel recognizes some special BPF types in map values or local
kptrs. Document that only bpf_spin_lock and bpf_timer will preserve
backwards compatibility, and kptr will preserve backwards compatibility
for the operations on the pointer, not the types supported for such
kptrs.
For local kptrs, document that there are no stability guarantees at all.
Finally, document that 'bpf_' namespace is reserved for adding future
special fields, hence BPF programs must not declare types with such
names in their programs and still expect backwards compatibility.

Commit 237405ebef58 ("arm64: cpufeature: Force HWCAP to be based on the
sysreg visible to user-space") forced the hwcaps to use sanitised
user-space view of the id registers. However, the ID register structures
used to select few compat cpufeatures (vfp, crc32, ...) are masked and
hence such hwcaps do not appear in /proc/cpuinfo anymore for PER_LINUX32
personality.
Add the ID register structures explicitly and set the relevant entry as
visible. As these ID registers are now of type visible so make them
available in 64-bit userspace by making necessary changes in register
emulation logic and documentation.
While at it, update the comment for structure ftr_generic_32bits[] which
lists the ID register that use it.

The queue configuration is referenced by snps,mtl-rx-config and
snps,mtl-tx-config. Some in-tree DTs and the example put the
referenced config nodes directly beneath the root node, but
most in-tree DTs put it as child node of the dwmac node.
This adds proper description for this setup, which has the
advantage of validating the queue configuration node content.
The example is also updated to use the sub-node style, incl.
the axi bus configuration node, which got the same treatment
as the queues config in 5361660af6d3 ("dt-bindings: net: snps,dwmac:
Document stmmac-axi-config subnode").

In sysfs, we use attribute name "cpumap" or "cpus" for cpu mask and
"cpulist" or "cpus_list" for cpu list. For example, in my system,
$ cat /sys/devices/system/node/node0/cpumap
f,ffffffff
$ cat /sys/devices/system/cpu/cpu2/topology/core_cpus
0,00100004
$ cat cat /sys/devices/system/node/node0/cpulist
0-35
$ cat /sys/devices/system/cpu/cpu2/topology/core_cpus_list
2,20
It looks reasonable to use "nodemap" for node mask and "nodelist" for
node list. So, rename the attribute to follow the naming convention.

PLB (Protective Load Balancing) is a host based mechanism for load
balancing across switch links. It leverages congestion signals(e.g. ECN)
from transport layer to randomly change the path of the connection
experiencing congestion. PLB changes the path of the connection by
changing the outgoing IPv6 flow label for IPv6 connections (implemented
in Linux by calling sk_rethink_txhash()). Because of this implementation
mechanism, PLB can currently only work for IPv6 traffic. For more
information, see the SIGCOMM 2022 paper:
https://doi.org/10.1145/3544216.3544226
This commit adds new sysctl knobs and sets their default values for
TCP PLB.

Marc Kleine-Budde says:
====================
this is a pull request of 29 patches for net-next/master.
The first patch is by Daniel S. Trevitz and adds documentation for
switchable termination resistors.
Zhang Changzhong's patch fixes a debug output in the j13939 stack.
Oliver Hartkopp finally removes the pch_can driver, which is
superseded by the generic c_can driver.
Gustavo A. R. Silva replaces a zero-length array with
DECLARE_FLEX_ARRAY() in the ucan driver.
Kees Cook's patch removes a no longer needed silencing of
"-Warray-bounds" warnings for the kvaser_usb driver.
The next 2 patches target the m_can driver. The first is by me cleans
up the LEC error handling, the second is by Vivek Yadav and extends
the LEC error handling to the data phase of CAN-FD frames.
The next 9 patches all target the gs_usb driver. The first 5 patches
are by me and improve the Kconfig prompt and help text, set
netdev->dev_id to distinguish multi CAN channel devices, allow
loopback and listen only at the same time, and clean up the
gs_can_open() function a bit. The remaining 4 patches are by Jeroen
Hofstee and add support for 2 new features: Bus Error Reporting and
Get State.
Jimmy Assarsson and Anssi Hannula contribute 10 patches for the
kvaser_usb driver. They first add Listen Only and Bus Error Reporting
support, handle CMD_ERROR_EVENT errors, improve CAN state handling,
restart events, and configuration of the bit timing parameters.
Another patch by me which fixes the indention in the m_can driver.
A patch by Dongliang Mu cleans up the ucan_disconnect() function in
the ucan driver.
The last patch by Biju Das is for the rcan_canfd driver and cleans up
the reset handling.
