netconsole: selftests: Move netconsole selftests to separate target

This patch moves netconsole selftests from drivers/net to its own target
in drivers/net/netconsole.

This change helps saving some resources from CI since tests in
drivers/net automatically run against real hardware which are not used
by netconsole tests as they rely solely on netdevsim.

lib_netcons.sh is kept under drivers/net/lib since it is also used by
bonding selftests. Finally, drivers/net config remains unchanged as
netpoll_basic.py requires netconsole (and does leverage real HW testing).

selftests: netconsole: ensure required log level is set on netcons_basic

This commit ensures that the required log level is set at the start of
the test iteration.

Part of the cleanup performed at the end of each test iteration resets
the log level (do_cleanup in lib_netcons.sh) to the values defined at the
time test script started. This may cause further test iterations to fail
if the default values are not sufficient.

selftests: net: Add IPv6 support to netconsole basic tests

Add IPv6 support to the netconsole basic functionality tests by:

- Introducing separate IPv4 and IPv6 address variables (SRCIP4/SRCIP6,
DSTIP4/DSTIP6) to replace the single SRCIP/DSTIP variables
- Adding select_ipv4_or_ipv6() function to choose protocol version
- Updating socat configuration to use UDP6-LISTEN for IPv6 tests
- Adding wait_for_port() wrapper to handle protocol-specific port waiting
- Expanding test matrix to run both basic and extended formats against
both IPv4 and IPv6 protocols
- Improving cleanup to kill any remaining socat processes
- Adding sleep delays for better IPv6 packet handling reliability

The test now validates netconsole functionality across both IP versions,
improving test coverage for dual-stack network environments.

This test would avoid the regression fixed by commit f59902070269 ("net:
netpoll: Initialize UDP checksum field before checksumming")

Extend the netconsole selftest to validate both basic and extended
target formats. The basic format is a simpler variant that doesn't
support userdata or release functionality.

The test now validates that netconsole works correctly in both
configurations, improving test coverage for different netconsole
deployment scenarios.

selftests: netconsole: Do not exit from inside the validation function

Remove the exit call from validate_result() function and move the
test exit logic to the main script. This allows the function to
be reused in scenarios where the test needs to continue execution
after validation, rather than terminating immediately.

The validate_result() function should focus on validation logic
only, while the calling script maintains control over program
flow and exit conditions. This change improves code modularity
and prepares for potential future enhancements where multiple
validations might be needed in a single test run.

netconsole: selftest: Split the helpers from the selftest

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.

net: netconsole: selftests: Check if netdevsim is available

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.

Adds a selftest that creates two virtual interfaces, assigns one to a

It listens on the destination interface using socat and configures a
dynamic target on netconsole, pointing to the destination IP address.

The test then checks if the message was received properly on the
destination interface.
