When parsing throws an exception one often has to figure out which
attribute couldn't be parsed from first principles. For families
with large message parsing trees like rtnetlink guessing the
attribute can be hard.
Print a bit of information as the exception travels out, e.g.:
# when dumping rt links
Error decoding 'flags' from 'linkinfo-ip6tnl-attrs'
Error decoding 'data' from 'linkinfo-attrs'
Error decoding 'linkinfo' from 'link-attrs'

The Traceback is what we would previously see, the "Error..."
messages are new. We print a message per level (in the stack
order). Printing single combined message gets tricky quickly
given sub-messages etc.

We stated in documentation [1] and previous discussions [2]
that the need for overriding fields in members of subsets
is anticipated. Implement it.
Since each attr is now a new object we need to make sure
that the modifications are propagated. Specifically C codegen
wants to annotate which attrs are used in requests and replies
to generate the right validation artifacts.

In commit d7811e623dd4 ("[NET]: Drop tx lock in dev_watchdog_up")
dev_watchdog_up() became a simple wrapper for __netdev_watchdog_up()
Herbert also said : "In 2.6.19 we can eliminate the unnecessary
__dev_watchdog_up and replace it with dev_watchdog_up."
This patch consolidates things to have only two functions, with
a common prefix.
- netdev_watchdog_up(), exported for the sake of one freescale driver.
This replaces __netdev_watchdog_up() and dev_watchdog_up().
- netdev_watchdog_down(), static to net/sched/sch_generic.c
This replaces dev_watchdog_down().

Introduce support for HTB Qdisc offload available in the Airoha EN7581
ethernet controller. EN7581 can offload only one level of HTB leafs.
Each HTB leaf represents a QoS channel supported by EN7581 SoC.
The typical use-case is creating a HTB leaf for QoS channel to rate
limit the egress traffic and attach an ETS Qdisc to each HTB leaf in
order to enforce traffic prioritization.

A few recently added packetdrill tests that are known time sensitive
(e.g., because testing timestamping) occasionally fail in debug mode:
https://netdev.bots.linux.dev/contest.html?executor=vmksft-packetdrill-dbg
These failures are well understood. Correctness of the tests is
verified in non-debug mode. Continue running in debug mode also, to
keep coverage with debug instrumentation.
But, only in debug mode, mark these tests with well understood
timing issues as XFAIL (known failing) rather than FAIL when failing.
Introduce an allow list xfail_list with known cases.
Expand the ktap infrastructure with XFAIL support.

Rule counter in matcher's struct is used in two places:
1. As heuristics to decide when the number of rules have crossed a
certain percentage threshold and the matcher should be resized.
We don't mind here if the number will be off by 1-2 due to concurrency.
2. When destroying matcher, the counter value is checked and the
user is warned if it is not 0. Here we lock all the queues, so the
counter will be correct.
We don't need to always have *exact* number, but we do need this
number to not be corrupted, which is what is happening when the
counter isn't atomic, due to update by different threads.

Instead of having a large array of action templates allocated with
kmalloc, have smaller array and allocate it with kvmalloc.
The size of the array represents the max number of AT attach
operations for the same matcher. This number is not expected
to be very high. In any case, when the limit is reached, the
next attempt to attach new AT will result in creation of a new
matcher and moving all the rules to this matcher.

Currently, when firmware failure occurs during matcher disconnect flow,
the error flow of the function reconnects the matcher back and returns
an error, which continues running the calling function and eventually
frees the matcher that is being disconnected.
This leads to a case where we have a freed matcher on the matchers list,
which in turn leads to use-after-free and eventual crash.
This patch fixes that by not trying to reconnect the matcher back when
some FW command fails during disconnect.
Note that we're dealing here with FW error. We can't overcome this
problem. This might lead to bad steering state (e.g. wrong connection
between matchers), and will also lead to resource leakage, as it is
the case with any other error handling during resource destruction.
However, the goal here is to allow the driver to continue and not crash
the machine with use-after-free error.

In pools, STCs and actions: no need to allocate array for various
table types, as HWS is used to manage only FDB flow tables.

Some HWS structs have refcounts that are just u32.
Comment how they are protected and add '__must_hold()'
annotation where applicable.

Add support for the PCS to specify which interfaces it supports, which
can be used by MAC drivers to build the main supported_interfaces
bitmap. Phylink also validates that the PCS returned by the MAC driver
supports the interface that the MAC was asked for.
An empty supported_interfaces bitmap from the PCS indicates that it
does not provide this information, and we handle that appropriately.
