AddedGratuitousARPAmbiguousTerminology

GratuitousARPAmbiguousTerminology is in public.mdIt has five bullets, each linking to where the topic is discussed: - requests, replies or both; - form or purpose; - gratuitous request or announcement. It also notes that Wireshark’s own announcement flag is narrower: a gratuitous request with Target MAC 00:00:00:00:00:00. - probes called gratuitous; - what these notes use.

Links to the new topic - GratuitousARPMessages: under the “Known as gratuitous ARP” line. - ARPAnnouncement: under its first line. - ARPProbe: under the line that calls a probe “gratuitous”. - UnicastGratuitousARPReply: a new line saying it’s not always gratuitous in the unsolicited sense. - Private GratuitousARPMessages: under the author’s comment quote.

Two new source topics in public.md, next to 20261007T080815: - 20261024T081249: RFC 5944, §1.6 and §4.6. - 20261024T081250: Wireshark’s packet-arp.c.

The “replies alone” claim in the collating topic has no @ref. Its source, 20261006T200503, is in private.md, and a public topic can’t link there.
