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.

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.

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.

Adds a selftest that creates two virtual interfaces, assigns one to a
new namespace, and assigns IP addresses to both.
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.

Add a selftest for netdev generic netlink. For now there is only a
single test that exercises the `queue-get` API.
The test works with netdevsim by default or with a real device by
setting NETIF.
Add a timeout param to cmd() since ethtool -L can take a long time on
real devices.

Add a very simple test for testing with a remote system.
Both IPv4 and IPv6 connectivity is optional, later change
will add checks to skip tests based on available addresses.
Using netdevsim:
$ ./run_kselftest.sh -t drivers/net:ping.py
TAP version 13
1..1
# timeout set to 45
# selftests: drivers/net: ping.py
# KTAP version 1
# 1..2
# ok 1 ping.test_v4
# ok 2 ping.test_v6
# # Totals: pass:2 fail:0 xfail:0 xpass:0 skip:0 error:0
ok 1 selftests: drivers/net: ping.py
Command line SSH:
$ NETIF=virbr0 REMOTE_TYPE=ssh REMOTE_ARGS=root@192.168.122.123 \
LOCAL_V4=192.168.122.1 REMOTE_V4=192.168.122.123 \
./tools/testing/selftests/drivers/net/ping.py
KTAP version 1
1..2
ok 1 ping.test_v4
ok 2 ping.test_v6 # SKIP Test requires IPv6 connectivity
# Totals: pass:1 fail:0 xfail:1 xpass:0 skip:0 error:0
Existing devices placed in netns (and using net.config):
$ cat drivers/net/net.config
NETIF=veth0
REMOTE_TYPE=netns
REMOTE_ARGS=red
LOCAL_V4="192.168.1.1"
REMOTE_V4="192.168.1.2"
$ ./run_kselftest.sh -t drivers/net:ping.py
TAP version 13
1..1
# timeout set to 45

Add drivers/net as a target for mixed-use tests.
The setup is expected to work similarly to the forwarding tests.
Since we only need one interface (unlike forwarding tests)
read the target device name from NETIF. If not present we'll
try to run the test against netdevsim.
