Squash to "selftests/bpf: Add bpf_red scheduler & test"

After squashing into this change, the patch "selftests/bpf: Add bpf_red test" can be merged into the patch "selftests/bpf: Add bpf_red scheduler" appending the following lines into commit log: ''' Using MPTCP_SCHED_TEST macro to add a new test for this bpf_red scheduler, the arguments "1 1" means data has been sent on both net devices. Run this test by RUN_MPTCP_TEST macro. ''' And update the subject to "selftests/bpf: Add bpf_red scheduler & test". Signed-off-by: Geliang Tang <[email protected]>
