This patch adds a selftest that verifies netconsole functionality
over bonded network interfaces using netdevsim. It sets up two bonded
interfaces acting as transmit (TX) and receive (RX) ends, placed in
separate network namespaces. The test sends kernel log messages and
verifies that they are properly received on the bonded RX interfaces
with both IPv4 and IPv6, and using basic and extended netconsole
formats.
This patchset aims to test a long-standing netpoll subsystem where
netpoll has multiple users. (in this case netconsole and bonding). A
similar selftest has been discussed in [1] and [2].
This test also tries to enable bonding and netpoll in different order,
just to guarantee that all the possibilities are exercised.

We get a significant number of conflicts between net and net-next
because of selftests Makefile changes. People tend to append new
test cases at the end of the Makefile when there's no clear sort
order. Sort all networking selftests Makefiles, use the following
format:
VAR_NAME := \
entry1 \
entry2 \
entry3 \
# end of VAR_NAME
Some Makefiles are already pretty close to this.

This introduces a test for IPSec offload over bonding, utilizing netdevsim
for the testing process, as veth interfaces do not support IPSec offload.
The test will ensure that the IPSec offload functionality remains operational
even after a failover event occurs in the bonding configuration.
Here is the test result:
TEST: bond_ipsec_offload (active_slave eth0) [ OK ]
TEST: bond_ipsec_offload (active_slave eth1) [ OK ]

Add comprehensive selftest to verify:
- Per-port actor priority setting via ad_actor_port_prio
- Aggregator selection behavior with port_priority ad_select policy
Also move cmd_jq helper from forwarding/lib.sh to net/lib.sh for
broader reusability across network selftests.
Here is the result output
# ./bond_lacp_prio.sh

Add a selftest to verify bonding behavior when `lacp_active` is set to `off`.
The test checks the following:
- The passive LACP bond should not send LACPDUs before receiving a partner's
LACPDU.
- The transmitted LACPDUs must not include the active flag.
- After transitioning to EXPIRED and DEFAULTED states, the passive side should
still not initiate LACPDUs.

commit 25ae948b4478 ("selftests/net: add lib.sh") added net/lib.sh to
contain code shared by tests under net/ and net/forwarding/. However, this
caused issues with selftests from directories other than net/forwarding/,
in particular those under drivers/net/. Those issues were avoided in a
simple way by duplicating some content in commit 2114e83381d3 ("selftests:
forwarding: Avoid failures to source net/lib.sh").
In order to remove the duplicated content, restore the inclusion of
net/lib.sh from net/forwarding/lib.sh but with the following changes:
* net/lib.sh is imported through the net_forwarding_dir path
The original expression "source ../lib.sh" would look for lib.sh in the
directory above the script file's one, which did not work for tests under
drivers/net/.
* net/lib.sh is added to TEST_INCLUDES
Since net/forwarding/lib.sh now sources net/lib.sh, both of those files
must be exported along with tests which source net/forwarding/lib.sh.

To improve the testing process for bond options, A new bond topology lib
is added to our testing setup. The current option_prio.sh file will be
renamed to bond_options.sh so that all bonding options can be tested here.
Specifically, for priority testing, we will run all tests using modes
1, 5, and 6. These changes will help us streamline the testing process
and ensure that our bond options are rigorously evaluated.

Add new network selftests for the bonding device which exercise the ether
type changing call paths. They also test for the recent syzbot bug[1] which
causes a warning and results in wrong device flags (IFF_SLAVE missing).
The test adds three bond devices and a nlmon device, enslaves one of the
bond devices to the other and then uses the nlmon device for successful
and unsuccesful enslaves both of which change the bond ether type. Thus
we can test for both MASTER and SLAVE flags at the same time.
If the flags are properly restored we get:
TEST: Change ether type of an enslaved bond device with unsuccessful enslave [ OK ]
TEST: Change ether type of an enslaved bond device with successful enslave [ OK ]

When exporting and running a subset of selftests via kselftest, files from
parts of the source tree which were not exported are not available. A few
tests are trying to source such files. Address the problem by using
symlinks.
The problem can be reproduced by running:
make -C tools/testing/selftests gen_tar TARGETS="drivers/net/bonding"
[... extract archive ...]
./run_kselftest.sh
or:
make kselftest KBUILD_OUTPUT=/tmp/kselftests TARGETS="drivers/net/bonding"

It looks like this test has been accidentally dropped when resolving
conflicts in this Makefile.
Most probably because there were 3 different patches modifying this file
in parallel:
commit 152e8ec77640 ("selftests/bonding: add a test for bonding lladdr target")
commit bbb774d921e2 ("net: Add tests for bonding and team address list management")
commit 2ffd57327ff1 ("selftests: bonding: cause oops in bond_rr_gen_slave_id")
The first one was applied in 'net-next' while the two other ones were
recently applied in the 'net' tree.
But that's alright, easy to fix by re-adding the missing one!
