Bastien Curutchet (eBPF Foundation) Feb. 19, 2025, 2:53 p.m. UTC 
Two subtests use the test_in_netns() function to run the test in a
dedicated network namespace. This can now be done directly through the
test_progs framework with a test name starting with 'ns_'.

Replace the use of test_in_netns() by test_ns_* calls.
