Howdy,

Please forgive what is hopefully not too naive of a question.

According to arp(4), the pseudo-device ether is used to map between 
10Mb/s Ethernet addresses and IP addresses.  PR docs/35604 was opened 
questioning whether this is true, or if it also supports 100Mb/s, and 
possibly also gigabit Ethernet.  I've searched Google and the mailing 
list archives, and haven't come upon an answer.

If the ether device doesn't support the 100/1000 addresses mapping, what 
does?  If it does support 100/1000, would it be accurate to change 
arp(4) to read:

The Address Resolution Protocol (ARP) is a protocol used to dynamically 
map between Internet host addresses and 10/100/1000Mb/s Ethernet 
addresses.  It is used by all the 10/100/1000Mb/s Ethernet interface 
drivers.  It is not specific to Internet protocols or to 10/100/1000Mb/s 
Ethernet, but this implementation currently supports only that combination.


   Thanks much,
  -Mike
