The testsuite already has simply tests for HSRv0. The testuite would
have been able to notice the v1 breakage if it was there at the time.

Extend the testsuite to also cover HSRv1.

Move the code and group into functions so it will be easier to extend
the test to HSRv1 so that both versions are covered.

Move the ping/test part into do_complete_ping_test() and the interface
setup into setup_hsr_interfaces().

The timeout in the while loop is never subtracted due wrong usage of
`let' leading to an endless loop if the former condition never gets
true.

Put the statement for let in quotes so it is parsed as a single
statement.

tls.sendmsg_large and tls.sendmsg_multiple are trying to send through
the self->cfd socket (only configured with TLS_RX) and to receive through
the self->fd socket (only configured with TLS_TX), so they're not using
kTLS at all. Swap the sockets.

We add these 8 test cases in bind_wildcard.c to check bind() conflicts.

  1st bind()          2nd bind()

All test passed without bhash2 and with bhash2 and this series.

This is a preparation patch for the following patch.

Let's define expected_errno in each test case so that we can add other test
cases easily.

The selftest passes the IPv6 address length for an IPv4 address.
We should pass the correct length.

Note inet_bind_sk() does not check if the size is larger than
sizeof(struct sockaddr_in), so there is no real bug in this
selftest.

Starting with v197, systemd uses predictable interface network names,
the traditional interface naming scheme (eth0) is deprecated, therefore
it cannot be assumed that the eth0 interface exists on the host.

This modification makes the bind_bhash test program run in a separate
network namespace and no longer needs to consider the name of the
network interface on the host.

The test uses perf stat to count the number of fib:fib_table_lookup
tracepoint hits for IPv4 and the number of fib6:fib6_table_lookup for
IPv6. The measured count is checked to be within 5% of the total number
of packets sent via veth1.
