Commit Message

Alexis Lothoré (eBPF Foundation) Nov. 13, 2024, 1:53 p.m. UTC
The flow_dissector test integrated in test_progs actually runs a wide
matrix of tests over different packets types and bpf programs modes, but
exposes only 3 main tests, preventing tests users from running specific
subtests with a specific input only.

Expose all subtests executed by flow_dissector by using
test__start_subtest().

This change resulsts in the exposure of 42 subtests with the current
