ACL: Fix next_table_index classifiers consistancy
Fixed consistancy between the first classifier match and the next_table_index classifier matches: - CLASSIFY_ACTION_SET_METADATA was applied only for the first classifier, but it was not applied for the other classifiers - Actions should be performed only for input ACLs - Payload should point at the IP header for output ACLs Change-Id: Ifbd7791756320ae3198520c41902f5e99e3d40b4 Signed-off-by: Gregory Thiemonge <gregory.thiemonge@enea.com>
