Howdy, Mark Tinguely tells me that ARP works for all speeds of Ethernet.

That last sentence seems wrong in light of the first two. I'm no expert, but I thought ARP was precisely specific to Ethernet. If that's correct, there's no "combination" left, and maybe the whole sentence is unneeded. It's not clear what the leftover would be trying to say. That ARP doesn't need to use Internet Protocol, but this implementation does? ?? It should be cleared up or cleared out. Thanks for the clarification. I've revised my patch to accurately reflect both what the ARP protocol does, and what the FreeBSD implementation does. Let me know how it looks. -Mike --- arp.4.old Thu Apr 4 11:09:54 2002 +++ arp.4 Thu Apr 4 15:01:34 2002 @@ -41,13 +41,14 @@ .Sh SYNOPSIS .Cd "pseudo-device ether" .Sh DESCRIPTION -The Address Resolution Protocol (ARP) is a protocol used to dynamically -map between Internet host addresses and 10Mb/s Ethernet addresses. -It is used by all the 10Mb/s Ethernet interface drivers. -It is not specific to Internet protocols or to 10Mb/s Ethernet, -but this implementation currently supports only that combination. +The Address Resolution Protocol (ARP) is used to dynamically +map between Protocol Addresses (such as IP addresses) and Local Network +Addresses (such as Ethernet addresses). +This implementation maps IP addresses to Ethernet, ARCnet, or Token Ring +addresses. +It is used by all the Ethernet interface drivers. .Pp -ARP caches Internet-Ethernet address mappings. +ARP caches address mappings.

This looks fine to me.
