   2==================================
   3
   4This is how they currently behave, not what the hardware can do--for example,
   5the Lance driver doesn't use its filter, even though the code for loading
   6it is in the DEC Lance-based driver.

   8The following are requirements for multicasting

  10AppleTalk       Multicast       hardware filtering not important but
  11                                 avoid cards only doing promisc
  12IP-Multicast    Multicast       hardware filters really help
  13IP-MRoute       AllMulti        hardware filters are of no help
