Subject: [PATCH bpf-next v3 05/14] selftests/bpf: expose all subtests from flow_dissector
Date: Wed, 20 Nov 2024 08:43:15 +0100	[thread overview]
Message-ID: <20241120-flow_dissector-v3-5-45b46494f937@bootlin.com> (raw)
In-Reply-To: <20241120-flow_dissector-v3-0-45b46494f937@bootlin.com>

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().

Acked-by: Stanislav Fomichev <sdf@fomichev.me>
Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore@bootlin.com>

Changes in v3:
-none

Changes in v2:
- fetch Acked-by tag

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