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.

9b29afa116 selftests: drv-net: give HW stats sync time extra 25% of margin
There are transient failures for devices which update stats
periodically, especially if it's the FW DMA'ing the stats
rather than host periodic work querying the FW. Wait 25%
longer than strictly necessary.

For devices which don't report stats-block-usecs we retain
25 msec as the default wait time (0.025sec == 20,000usec * 1.25).

3f74d5bb80 selftests/net: Add env for container based tests
Add an env NetDrvContEnv for container based selftests. This automates
the setup of a netns, netkit pair with one inside the netns, and a BPF
program that forwards skbs from the NETIF host inside the container.

Currently only netkit is used, but other virtual netdevs e.g. veth can
be used too.

Expect netkit container datapath selftests to have a publicly routable
IP prefix to assign to netkit in a container, such that packets will
land on eth0. The BPF skb forward program will then forward such packets
from the host netns to the container netns.

9086984ff5 selftests: drv-net: psp: Better control the used PSP dev
The PSP responder fails when zero or multiple PSP devices are detected.
There's an option to select the device id to use (-d) but it's
currently not used from the PSP self test. It's also hard to use because
the PSP test doesn't dump the PSP devices so can't choose one.
When zero devices are detected, psp_responder fails which will cause the
parent test to fail as well instead of skipping PSP tests.

Fix both of these problems. Change psp_responder to:
- not fail when no PSP devs are detected.
- get an optional -i ifindex argument instead of -d.
- select the correct PSP dev from the dump corresponding to ifindex or
- select the first PSP dev when -i is not given.
- fail when multiple devs are found and -i is not given.
- warn and continue when the requested ifindex is not found.

Also plumb the ifindex from the Python test.

With these, when there are no PSP devs found or the wrong one is chosen,
psp_responder opens the server socket, listens for control connections
normally, and leaves the skipping of the various test cases which
require a PSP device (~most, but not all of them) to the parent test.
This results in output like:

ok 1 psp.test_case # SKIP No PSP devices found
[...]
ok 12 psp.dev_get_device # SKIP No PSP devices found
ok 13 psp.dev_get_device_bad
ok 14 psp.dev_rotate # SKIP No PSP devices found
[...]

The single letter + "path" helpers do not have many fans (see Link).
Use a Path object with a better name. test_dir is the replacement
for rpath(), net_lib_dir is a new path of the $ksft/net/lib directory.

The Path() class overloads the "/" operator and can be cast to string
automatically, so to get a path to a file tests can do:

    path = env.test_dir / "binary"

31611cea8f selftests: drv-net: add a TCP ping test case (and useful helpers)
More complex tests often have to spawn a background process,
like a server which will respond to requests or tcpdump.

Add support for creating such processes using the with keyword:

  with bkg("my-daemon", ..):
     # my-daemon is alive in this block

My initial thought was to add this support to cmd() directly
but it runs the command in the constructor, so by the time
we __enter__ it's too late to make sure we used "background=True".

Second useful helper transplanted from net_helper.sh is
wait_port_listen().

The test itself uses socat, which insists on v6 addresses
being wrapped in [], it's not the only command which requires
this format, so add the wrapped address to env. The hope
is to save test code from checking if address is v6.

1880f272d2 selftests: drv-net: construct environment for running tests which require an endpoint
Nothing surprising here, hopefully. Wrap the variables from
the environment into a class or spawn a netdevsim based env
and pass it to the tests.

5433892950 selftests: drv-net: factor out parsing of the env
The tests with a remote end will use a different class,
for clarity, but will also need to parse the env.
So factor parsing the env out to a function.

b4db9f8402 selftests: drivers: add scaffolding for Netlink tests in Python
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.
