26555673bc selftests: Add MACsec VLAN propagation traffic test 
Add VLAN filter propagation tests through offloaded MACsec devices via
actual traffic.

The tests create MACsec tunnels with matching SAs on both endpoints,
stack VLANs on top, and verify connectivity with ping. Covered:
- Offloaded MACsec with VLAN (filters propagate to HW)
- Software MACsec with VLAN (no HW filter propagation)
- Offload on/off toggle and verifying traffic still works

On netdevsim this makes use of the VLAN filter debugfs file to actually
validate that filters are applied/removed correctly.
On real hardware the traffic should validate actual VLAN filter
propagation.

e1ab601bb2 selftests: Migrate nsim-only MACsec tests to Python 
Move MACsec offload API and ethtool feature tests from
tools/testing/selftests/drivers/net/netdevsim/macsec-offload.sh to
tools/testing/selftests/drivers/net/macsec.py using the NetDrvEnv
framework so tests can run against both netdevsim (default) and real
hardware (NETIF=ethX). As some real hardware requires MACsec to use
encryption, add that to the tests.

Netdevsim-specific limit checks (max SecY, max RX SC) were moved into
separate test cases to avoid failures on real hardware.

47f78a67d3 selftests: drv-net: Enable BTF 
Commit fec2e55bdef ("selftests: drv-net: Pull data before parsing headers")
added __ksym external symbol to xdp_native.bpf.c which now requires
a kernel with BTF. Enable BTF for driver selftests.

788e52e2b6 selftests: drv-net: Test queue xsk attribute 
Test that queues which are used for AF_XDP have the xsk nest attribute.
The attribute is currently empty, but its existence means the AF_XDP is
being used for the queue. Enable CONFIG_XDP_SOCKETS for
selftests/drivers/net tests, as well.

b494b16738 net: netconsole: selftests: Create a new netconsole selftest 
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.

438ce84bae selftests: drv-net: add config for netdevsim 
Real driver testing will obviously require enabling more
options, but will require more manual setup in the first
place. For CIs running purely software tests we need
to enable netdevsim.
