Totals currently only pay attention to exceptions, if check fails
(say ksft_eq()) the test case will be counted as pass:
# At /ksft/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:3 fail:0 xfail:0 xpass:0 skip:0 error:0
^^^^^^^^^^^^^
Pay attention to the result.

ping prints all the info to stdout. To make debug easier capture
stdout in the Exception raised when command unexpectedly fails.

Add a Python test for the basic ops.

KTAP version 1

ok 2 nl_netdev.lo_check
ok 3 nl_netdev.page_pool_check

Using "with" on an entire driver test env is supported already,
but it's also useful to use "with" on an individual nsim.

Instead of a summary line print the full exception.
This makes debugging Python tests much easier.

Developing Python tests is a bit annoying because when test fails
we only print the fail message and no info about which exact check
led to it. Print the location (the first line of this example is new):
# At /root/ksft-net-drv/./net/nl_netdev.py line 38:
# Check failed 0 != 10
not ok 3 nl_netdev.page_pool_check

net/lib/py/nsim.py already contains the most useful parts
of the netdevsim wrapper classes. Reuse them.

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.

Add glue code for accessing the YNL library which lives under
tools/net and YAML spec files from under Documentation/.
Automatically figure out if tests are run in tree or not.
Since we'll want to use this library both from net and
drivers/net test targets make the library a target as well,
and automatically include it when net or drivers/net are
included. Making net/lib a target ensures that we end up
with only one copy of it, and saves us some path guessing.
Add a tiny bit of formatting support to be able to output KTAP
from the start.
