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.

Sort config files for networking selftests. This should help us
avoid merge conflicts between net and net-next. patchwork check
will be added to prevent new issues.

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 a vlan over bond testing to make sure arp/ns target works.
Also change all the configs to mudules.

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.

As a followup to commit 03fb8565c880 ("selftests: bonding: add missing
build configs"), add more networking-specific config options which are
needed for bonding tests.
For testing, I used the minimal config generated by virtme-ng and I added
the options in the config file. All bonding tests passed.

bonding tests also try to create bridge, veth and dummy
interfaces. These are not currently listed in config.

Test that the bonding and team drivers clean up an underlying device's
address lists (dev->uc, dev->mc) when the aggregated device is deleted.
Test addition and removal of the LACPDU multicast address on underlying
devices by the bonding driver.
v2:
* add lag_lib.sh to TEST_FILES
v3:
* extend bond_listen_lacpdu_multicast test to init_state up and down cases
* remove some superfluous shell syntax and 'set dev ... up' commands

This creates a test collection in drivers/net/bonding for bonding
specific kernel selftests.
The first test is a reproducer that provisions a bond and given the
specific order in how the ip-link(8) commands are issued the bond never
transmits an LACPDU frame on any of its slaves.
