The tool pp_alloc_fail.py tested error recovery by injecting errors
into the function page_pool_alloc_pages(). The page pool allocation
function page_pool_dev_alloc() does not end up calling
page_pool_alloc_pages(). page_pool_alloc_netmems() seems to be the
function that is called by all of the page pool alloc functions in
the API, so move error injection to that function instead.

HDS/HDS-thresh features were updated/implemented. so add some tests for
these features.
HDS tests are the same with `ethtool -G eth0 tcp-data-split <on | off |
auto >` but `auto` depends on driver specification.
So, it doesn't include `auto` case.
HDS-thresh tests are same with `ethtool -G eth0 hds-thresh <0 - MAX>`
It includes both 0 and MAX cases. It also includes exceed case, MAX + 1.

Running "make kselftest TARGETS=net/forwarding" results in
multiple ccurrences of the same error:
- ./lib.sh: line 787: teamd: command not found
This patch adds the variable $REQUIRE_TEAMD in every test that uses the
command teamd and checks the $REQUIRE_TEAMD variable in the file "lib.sh"
to skip the test if the command is not installed.

Because of patch[1] the graft behaviour changed
So the command:
tcq replace parent 100:1 handle 204:
Is no longer valid and will not delete 100:4 added by command:
tcq replace parent 100:4 handle 204: pfifo_fast
So to maintain the original behaviour, this patch manually deletes 100:4
and grafts 100:1
Note: This change will also work fine without [1]

Add a new selftest for netconsole that tests the userdata entry limit
functionality. The test performs two key verifications:
1. Create MAX_USERDATA_ITEMS (16) userdata entries successfully
2. Confirm that attempting to create an additional userdata entry fails
The selftest script uses the netcons library and checks the behavior
by attempting to create entries beyond the maximum allowed limit.

Modify the cleanup function to remove all userdata keys created during the
test, instead of just deleting a single predefined key. This ensures a
more thorough cleanup of temporary resources.
Move the KEY_PATH variable definition inside the set_user_data function
to reduce global variables and improve encapsulation. The KEY_PATH
variable is now dynamically created when setting user data.
This change has no effect on the current test, while improving an
upcoming test that would create several userdata entries.

Split helper functions from the netconsole basic test into a separate
library file to enable reuse across different netconsole tests. This
change only moves the existing helper functions to lib/sh/lib_netcons.sh
while preserving the same test functionality.
The helpers provide common functions for:
- Setting up network namespaces and interfaces
- Managing netconsole dynamic targets
- Setting user data
- Handling test dependencies
- Cleanup operations
Do not make any change in the code, other than the mechanical
separation.

Most of our tests use rtnetlink to read device stats, so they
don't expose the drivers much to paths in which device stats
are read under RCU. Add tests which hammer profcs reads to
make sure drivers:
- don't sleep while reporting stats,
- can handle parallel reads,
- can handle device going down while reading.
Set ifname on the env class in NetDrvEnv, we already do that
in NetDrvEpEnv.

This test already catches a netlink bug fixed by this series,
but only when running on HW with many queues. Make sure the
netdevsim instance created has a lot of queues, and constrain
the size of the recv_buffer used by netlink.
While at it test both rx and tx queues.

The netconsole selftest relies on the availability of the netdevsim module.
To ensure the test can run correctly, we need to check if the netdevsim
module is either loaded or built-in before proceeding.
Update the netconsole selftest to check for the existence of
the /sys/bus/netdevsim/new_device file before running the test. If the
file is not found, the test is skipped with an explanation that the
CONFIG_NETDEVSIM kernel config option may not be enabled.

2. Writing a known value to the key
3. Validating the key-value pair appears in the captured network output

Note that the start_traffic commands in __burst_test() are each sending a

do not need a matching stop_traffic.

Instead of having a suite of dedicated cleanup functions, use the defer
framework to schedule cleanups right as their setup functions are run.
The sleep after stop_traffic() in mlxsw selftests is necessary, but
scheduling it as "defer sleep; defer stop_traffic" is silly. Instead, add a
local helper to stop traffic and sleep afterwards.
