Description Christian Weisgerber 2000-10-16 02:40:01 UTC 
The arp(4) man page erroneously claims that ARP is only used over
10Mb/s Ethernet.

Pointed out by Hans-Guenter Weigand <hgw@d1906.inka.de> and

I'll agree that the manpage is somewhat confusing and even agree with
the change, but I will point out that this is technicaly correct.  If
you look at the arp hardware type list maintained by iana at
ftp://ftp.isi.edu/in-notes/iana/assignments/arp-parameters
you will notice that the hardware number for ethernet is specificaly
assigned to 10Mbps ethernet.  This is a strange by product of the shear
ancientness of the ARP protocol.  ARP continues to work at 100 and 1000 
Mbps because Ethernet is backwards compatable.
