If the testing kernel doesn't support setting fdb_max_learned or show fdb_n_learned, just skip it. Or we will get errors like ./bridge_fdb_learning_limit.sh: line 218: [: null: integer expression expected ./bridge_fdb_learning_limit.sh: line 225: [: null: integer expression expected Fixes: 6f84090333bb ("selftests: forwarding: bridge_fdb_learning_limit: Add a new selftest") Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> --- .../forwarding/bridge_fdb_learning_limit.sh | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+)
