interface
This patch finalizes the transition to work with a single local
interface for the ethtool_rmon.sh test. Each 'ip link' and 'ethtool'
command used by the test is annotated with the necessary run_on in
order to be executed on the necessary target system, be it local, in
another network namespace or through ssh.
Since we need NETIF up and running also for control traffic, we now
expect that the interfaces are up and running and do not touch bring
them up or down at the end of the test. This is also documented in the
drivers/net/README.rst.
The ethtool_rmon.sh script can still be used in the older fashion by
passing two interfaces as command line arguments, the only restriction
is that those interfaces need to be already up.
$ DRIVER_TEST_CONFORMANT=no ./ethtool_rmon.sh eth0 eth1
As part of the kselftest infrastructure, this test can be run in the
following manner:
$ make -C tools/testing/selftests/ TARGETS="drivers/net drivers/net/hw" \
install INSTALL_PATH=/tmp/ksft-net-drv
$ cd /tmp/ksft-net-drv/
$ cat > ./drivers/net/net.config <<EOF

Update the ethtool_rmon.sh test so that it uses the KTAP format for its
output. This is achieved by using the helpers found in ktap_helpers.sh.
An example output can be found below.

The ethtool_rmon.sh script checks that the number of packets sent /
received during a test matches the expected value with a 1% tolerance.
Since in the next patches this test will gain the capability to also be
run on systems with a single interface where the traffic generator is
accesible through ssh, use the UINT32_MAX as the upper limit. This is
necessary since the same interface will be used also for control traffic
(the ssh commands) as well as the mausezahn generated one.

The selftests in drivers/net are slowly transitioning to being able to
be used on systems with a single network interface. The first step for the
ethtool_rmon.sh test is to only validate that the rmon counters are
properly exported on the first interface supplied as an argument.
Remove the rmon_histogram calls which intend to test also the rmon
counters on the 2nd interface. This also removes the need for the remote
system, which should be used only to inject traffic, to also support
rmon counters.

If run on the ethtool_rmon.sh script, shellcheck generates a bunch of
false positive errors. Suppress those checks that generate them.
Also cleanup the remaining warnings by using double quoting around the
used variables.

When rx-pktsNtoM reports a range that involves very low-valued range, such
as 0-64, the calculated length of the packet will be -4, because FCS is
subtracted from the value. mausezahn then confuses the value for an option
and bails out. As a result, the test dumps many mausezahn error messages.
Instead, cap the value at 0. mausezahn will use an appropriate minimum
packet length.

The SKIP return should be used for cases where tooling of the machine under
test is lacking. For cases where HW is lacking, the appropriate outcome is
XFAIL.
This is the case with ethtool_rmon and mlxsw_lib. For these, introduce a
new helper, log_test_xfail().
Do the same for router_mpath_nh_lib. Note that it will be fixed using a
more reusable way in a following patch.
For the two resource_scale selftests, the log should simply not be written,
because there is no problem.

The tests in net/forwarding are generally expected to be HW-independent.
There are however several tests that, while not depending on any HW in
particular, nevertheless depend on being used on HW interfaces. Placing
these selftests to net/forwarding is confusing, because the selftest will
just report it can't be run on veth pairs. At the same time, placing them
to a particular driver's selftests subdirectory would be wrong.
Instead, add a new directory, drivers/net/hw, where these generic but HW
independent selftests should be placed. Move over several such tests
including one helper library.
Since typically these tests will not be expected to run, omit the directory
drivers/net/hw from the TARGETS list in selftests/Makefile. Retain a
Makefile in the new directory itself, so that a user can make -C into that
directory and act on those tests explicitly.
