Convert tc.c and tc-filter-add.c to produce KTAP output with
kselftest_harness. Merge the two tests together. They both
test TC one is testing qdisc and the other classifiers but
they can easily live in a single selftest.
Make the test spawn a new netns, and run the operations on
lo to avoid onerous setup and cleanup.

Convert rt-link.c to use kselftest_harness.h with FIXTURE/TEST_F.
Move rt-link from BINS to TEST_GEN_PROGS.

Convert ovs.c to produce KTAP output with kselftest_harness.
The single "crud" test creates a new OVS datapath, fetches it back
by name, then dumps all datapaths verifying the new one appears.
IIRC I added this test because ovs is a genetlink family but
has a family-specific fixed header.

Add a test framework for YAML Netlink (YNL) tools, covering both CLI and
ethtool functionality. The framework includes:
1) cli: family listing, netdev, ethtool, rt-* families, and nlctrl
operations
2) ethtool: device info, statistics, ring/coalesce/pause parameters, and
feature gettings
The current YNL syntax is a bit obscure, and end users may not always know
how to use it. This test framework provides usage examples and also serves
as a regression test to catch potential breakages caused by future changes.
