nf_conntrack_udp_timeout sysctl only exist once conntrack module is loaded,
if this test runs standalone on a modular kernel sysctl setting fails,
this can result in test failure as udp conntrack entries expire too fast.

Use socat, like most of the other scripts already do. This also makes
the script complete slightly faster (3s -> 1s).
iperf3 establishes two connections (1 control connection, and 1+x
depending on test), so adjust expected counter values as well.

br_netfilter: If we can't add the needed initial nftables ruleset skip the
test, kernel doesn't support a required feature.
rpath: run a subset of the tests if possible, but make sure we return
the skip return value so they are marked appropriately by the kselftest
framework.
nft_audit.sh: provide version information when skipping, this should
help catching kernel problem (feature not available in kernel) vs.

Use busywait helper instead of unconditional sleep, reduces run time

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.

While writing tests with a lot more cases I got tired of having
to jump back and forth to add the name of the test to the ksft_run()
list. Most unittest frameworks do some name matching, e.g. assume
that functions with names starting with test_ are test cases.
Support similar flow in ksft_run(). Let the author list the desired
prefixes. globals() need to be passed explicitly, IDK how to work
around that.

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

# timeout set to 45
# selftests: drivers/net: ping.py
# KTAP version 1

# 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 \

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

Define the remote endpoint "model". To execute most meaningful device
driver tests we need to be able to communicate with a remote system,
and have it send traffic to the device under test.
Various test environments will have different requirements.
0) "Local" netdevsim-based testing can simply use net namespaces.
netdevsim supports connecting two devices now, to form a veth-like
construct.
1) Similarly on hosts with multiple NICs, the NICs may be connected
together with a loopback cable or internal device loopback.
One interface may be placed into separate netns, and tests
would proceed much like in the netdevsim case. Note that
the loopback config or the moving of one interface
into a netns is not expected to be part of selftest code.
2) Some systems may need to communicate with the remote endpoint
via SSH.
3) Last but not least environment may have its own custom communication
method.
Fundamentally we only need two operations:
- run a command remotely
- deploy a binary (if some tool we need is built as part of kselftests)
Wrap these two in a class. Use dynamic loading to load the Remote
class. This will allow very easy definition of other communication
methods without bothering upstream code base.
Stick to the "simple" / "no unnecessary abstractions" model for
referring to the remote endpoints. The host / remote object are
passed as an argument to the usual cmd() or ip() invocation.
For example:
ip("link show", json=True, host=remote)

Add a "--multi <do-op> <json>" command line to ynl that makes it
possible to add several operations to a single netlink request payload.
The --multi command line option is repeated for each operation.
This is used by the nftables family for transaction batches. For
example:
./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/nftables.yaml \
--multi batch-begin '{"res-id": 10}' \
--multi newtable '{"name": "test", "nfgen-family": 1}' \
--multi newchain '{"name": "chain", "table": "test", "nfgen-family": 1}' \
--multi batch-end '{"res-id": 10}'
[None, None, None, None]
It can also be used for bundling get requests:
./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/nftables.yaml \
--multi gettable '{"name": "test", "nfgen-family": 1}' \
--multi getchain '{"name": "chain", "table": "test", "nfgen-family": 1}' \
--output-json
[{"name": "test", "use": 1, "handle": 1, "flags": [],
"nfgen-family": 1, "version": 0, "res-id": 2},
{"table": "test", "name": "chain", "handle": 1, "use": 0,
"nfgen-family": 1, "version": 0, "res-id": 2}]

Test cases need to exit with non-zero status if they failed,
we currently don't do that:
# KTAP version 1
# 1..3
# # At /root/ksft-net-drv/drivers/net/./ping.py line 18:
# # Check failed 1 != 2
# not ok 1 ping.test_v4
# ok 2 ping.test_v6
# ok 3 ping.test_tcp
# # Totals: pass:2 fail:1 xfail:0 xpass:0 skip:0 error:0
ok 1 selftests: drivers/net: ping.py
^^^^
It's a bit tempting to make the exit part of ksft_run(),
but that only works well for very trivial setups. We can
revisit this later, if people forget to call ksft_exit().

Totals currently only pay attention to exceptions, if check fails

ok 2 ping.test_v6
ok 3 ping.test_tcp

Character sequences starting with `\` are interpreted by python as

regular expressions (e.g: "\d").
It seems Python >= 3.12 starts emitting a SyntaxWarning when these
escaped sequences are not recognized as valid Unicode characters.
An example of these warnings:

ping prints all the info to stdout. To make debug easier capture

As the buffer was already pre-printed into, print it as a string
rather than a format-string.

Here the selftests lib parses header name, while expectes non-space word
ending with a column.

Currently, "active reset" cases are flaky, because select() is called
for 3 sockets, while only 2 are expected to receive RST.
The idea of the third socket was to get into request_sock_queue,
but the test mistakenly attempted to connect() after the listener
socket was shut down.
Repair this test, it's important to check the different kernel
code-paths for signing RST TCP-AO segments.

The ethtool dump includes the lanes parameter only when the port is up.
Therefore, the ethtool_lanes.sh test waits for ports to come before testing
the lanes parameter.
In some cases, the test considers the port as up, but the lanes parameter
is not yet dumped although assumed to be, resulting in ethtool_lanes.sh
test failure.
To avoid that, ensure that the lanes parameter is indeed dumped by waiting
for it explicitly, before preforming the test cases.

The tests use the constant TC_HIT_TIMEOUT when waiting on the counter
values. However it does not include tc_common.sh where the counter is
specified. The test has been robust in our testing, which means the counter
is bumped quickly enough that the updated value is available already on the
first iteration. Nevertheless it's not correct. Include tc_common.sh as
appropriate.
