Yes, but I'm told it's slow. Based on questions coming in.

I'll try but I'm not really sure.

Depending on the gear used, normally the MAC address is stored at the router 
level in a table that matches it to IP address.  The MAC, I dont think is sent 
past that point.  

For 'ethernet interface' you have to be more specific.  Router?  Switch?  'dumb 
hub'?  HDLC isnt one I am up on but ARP is I believe done at the router level, 
via those same tables.
