title: Can two Ethernet MAC chips be connected directly (without going thru PHY)?
body: <p>I have two Application processors that I would like to connect to using Ethernet connection. both of these AP are about 15 inches apart.
  Both of these processors have built in Ethernet MAC.
  Typical way is to add in an Externet Eth PHY IC on both sides.</p>
  
  <p>Is it possible for me to ditch the Ethernet PHY totally and just connect the Eth MAC using MII interface directly?</p>
