Created attachment 204623 [details] patch to arp.8 Currently, the meaning of -a is not clear - will arp -a display or delete? I think either the deletion behaviour could just be mentioned under -d (not under -a at all) or something like the following patch that tries to indicate the conditions under which -a does deletion.
