There is a desire for the felix driver to gain support for multiple
tag_8021q CPU ports, but the current model prevents it.
This is because ocelot_apply_bridge_fwd_mask() only takes into
consideration whether a port is a tag_8021q CPU port, but not whose CPU
port it is.
We need a model where we can have a direct affinity between an ocelot
port and a tag_8021q CPU port. This serves as the basis for multiple CPU
ports.
Declare a "dsa_8021q_cpu" backpointer in struct ocelot_port which
encodes that affinity. Repurpose the "ocelot_set_dsa_8021q_cpu" API to
"ocelot_assign_dsa_8021q_cpu" to express the change of paradigm.
Note that this change makes the first practical use of the new
ocelot_port->index field in ocelot_port_unassign_dsa_8021q_cpu(), where
we need to remove the old tag_8021q CPU port from the reserved VLAN range.

tag_8021q CPU
Add more logic to ocelot_port_{,un}set_dsa_8021q_cpu() from the ocelot
switch lib by encapsulating the ocelot_apply_bridge_fwd_mask() call that
felix used to have.
This is necessary because the CPU port change procedure will also need
to do this, and it's good to reduce code duplication by having an entry
point in the ocelot switch lib that does all that is needed.

Most protocol-specific pointers in struct net_device are under
a respective ifdef. Wireless is the notable exception. Since
there's a sizable number of custom-built kernels for datacenter
workloads which don't build wireless it seems reasonable to
ifdefy those pointers as well.
While at it move IPv4 and IPv6 pointers up, those are special
for obvious reasons.

Fix the decision on when to generate an IDLE ACK by keeping a count of the
number of packets we've received, but not yet soft-ACK'd, and the number of
packets we've processed, but not yet hard-ACK'd, rather than trying to keep
track of which DATA sequence numbers correspond to those points.
We then generate an ACK when either counter exceeds 2. The counters are
both cleared when we transcribe the information into any sort of ACK packet
for transmission. IDLE and DELAY ACKs are skipped if both counters are 0
(ie. no change).

There's a locking issue with the per-netns list of calls in rxrpc. The
pieces of code that add and remove a call from the list use write_lock()
and the calls procfile uses read_lock() to access it. However, the timer
callback function may trigger a removal by trying to queue a call for
processing and finding that it's already queued - at which point it has a
spare refcount that it has to do something with. Unfortunately, if it puts
the call and this reduces the refcount to 0, the call will be removed from
the list. Unfortunately, since the _bh variants of the locking functions
aren't used, this can deadlock.

The driver will be able to send notification events towards
a user process, using user's registered event file descriptor.
The driver uses the notification mechanism to inform the
user about an occurred event.
A user thread can wait until a notification is received from
the driver.
The driver stores the occurred event until the user reads it,
using HL_INFO_GET_EVENTS - new ioctl opcode in the INFO ioctl.
Gaudi specific implementation includes sending a notification
on a TPC assertion event that is received from f/w.

We currently have one tcp bind table (bhash) which hashes by port
number only. In the socket bind path, we check for bind conflicts by
traversing the specified port's inet_bind2_bucket while holding the
bucket's spinlock (see inet_csk_get_port() and inet_csk_bind_conflict()).
In instances where there are tons of sockets hashed to the same port
at different addresses, checking for a bind conflict is time-intensive
and can cause softirq cpu lockups, as well as stops new tcp connections
since __inet_inherit_port() also contests for the spinlock.
This patch proposes adding a second bind table, bhash2, that hashes by
port and ip address. Searching the bhash2 table leads to significantly
faster conflict resolution and less time holding the spinlock.

Add nvme_fc_io_getuuid() to the nvme-fc transport. The routine is invoked
by the FC LLDD on a per-I/O request basis. The routine translates from the
FC-specific request structure to the bio and the cgroup structure in order
to obtain the FC appid stored in the cgroup structure. If a value is not
set or a bio is not found, a NULL appid (aka uuid) will be returned to the
LLDD.

When doing DP AUX transfers there are two actors that need to be
powered in order for the DP AUX transfer to work: the DP source and
the DP sink. Commit bacbab58f09d ("drm: Mention the power state
requirement on side-channel operations") added some documentation
saying that the DP source is required to power itself up (if needed)
to do AUX transfers. However, that commit doesn't talk anything about
the DP sink.
For full fledged DP the sink isn't really a problem. It's expected
that if an external DP monitor isn't plugged in that attempting to do
AUX transfers won't work. It's also expected that if a DP monitor is
plugged in (and thus asserting HPD) then AUX transfers will work.
When we're looking at eDP, however, things are less obvious. Let's add
some documentation about expectations. Here's what we'll say:
1. We don't expect the DP AUX transfer function to power on an eDP
panel. If an eDP panel is physically connected but powered off then it
makes sense for the transfer to fail.
2. We'll document that the official way to power on a panel is via the
bridge chain, specifically by making sure that the panel's prepare
function has been called (which is called by
panel_bridge_pre_enable()). It's already specified in the kernel doc
of drm_panel_prepare() that this is the way to power the panel on and
also that after this call "it is possible to communicate with any
integrated circuitry via a command bus."
3. We'll also document that for code running in the panel driver
itself that it is legal for the panel driver to power itself up
however it wants (it doesn't need to officially call
drm_panel_pre_enable()) and then it can do AUX bus transfers. This is
currently the way that edp-panel works when it's running atop the DP
AUX bus.
NOTE: there was much discussion of all of this in response to v1 [1]
of this patch. A summary of that is:
* With the Intel i195 driver, apparently eDP panels do get powered
up. We won't forbid this but it is expected that code that wants to
run on a variety of platforms should ensure that the drm_panel's
prepare() function has been called.
* There is at least a reasonable amount of agreement that the
transfer() functions itself shouldn't be responsible for powering
the panel. It's proposed that if we need the DP AUX dev nodes to be
robust for eDP that the code handling the DP AUX dev nodes could
handle powering the panel by ensuring that the panel's prepare()
call was made. Potentially drm_dp_aux_dev_get_by_minor() could be a
good place to do this. This is left as a future exercise. Until
that's fixed the DP AUX dev nodes for eDP are probably best just
used for debugging.
* If a panel could be in PSR and DP AUX via the dev node needs to be
reliable then we need to be able to pull the panel out of PSR. On
i915 this is also apparently handled as part of the transfer()
function.

PTP one step sync packets cannot have CSUM padding and insertion in
SW since time stamp is inserted on the fly by HW.
In addition, ptp4l version 3.0 and above report an error when skb
timestamps are reported for packets that not processed for TX TS
after transmission.
Add a helper to identify PTP one step sync and fix the above two
errors. Add a common mask for PTP header flag field "twoStepflag".
Also reset ptp OSS bit when one step is not selected.

Oliver Hartkopp contributes a patch for the ISO-TP CAN protocol to
update the validation of address information during bind.
The next patch is by Jakub Kicinski and converts the CAN network
drivers from netif_napi_add() to the netif_napi_add_weight() function.
Another patch by Oliver Hartkopp removes obsolete CAN specific LED
support.

This patch set implements kexec_file_load() for RISC-V, which is
currently only allowed on rv64 due to some minor build issues on 32-bit
platforms in the generic code. This allows users to kexec() using an FD
as opposed to a buffer.

Because GCC-12 is fully stupid about array bounds and it's just really
hard to get a solid array definition from a linker script, flip the
array order to avoid needing negative offsets :-/
This makes the whole relational pointer magic a little less obvious, but
alas.
