    sys/net              if_ethersubr.c 
  Log:
  Extend the interface to ether_input(): a NULL eh pointer means that
  the mbuf contains the ethernet header (eh) as well, which ether_input()
  will strip off as needed.
  
  This permits the removal (in a backward compatible way) of the
  header removal code which right now is replicated in all drivers,
  sometimes in an inconsistent way. Also, because many functions
  called after ether_input() require the eh in the mbuf, eventually
  we can propagate the interface and handle outdated drivers just
  in ether_input().
  
  Individual driver changes to use the new interface will follow as
  we have a chance to touch them.
  
  NOTE THAT THIS CHANGE IS FULLY BACKWARD COMPATIBLE AND DOES NOT BREAK
  BINARY COMPATIBILITY FOR DRIVERS.
