    selftests/net: plug rxtimestamp test into kselftest framework · 0558c396
    tannerlove authored
    Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add
    new rxtimestamp.sh wrapper script, so that the test runs isolated
    from background traffic in a private network namespace.
    
    Also ignore failures of test case #6 by default. This case verifies
    that a receive timestamp is not reported if timestamp reporting is
    enabled for a socket, but generation is disabled. Receive timestamp
    generation has to be enabled globally, as no associated socket is
    known yet. A background process that enables rx timestamp generation
    therefore causes a false positive. Ntpd is one example that does.
    
    Add a "--strict" option to cause failure in the event that any test
    case fails, including test #6. This is useful for environments that
    are known to not have such background processes.
    
    Tested:
    make -C tools/testing/selftests TARGETS="net" run_tests
