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

   8 The following are requirements for multicasting
   9 -----------------------------------------------
  10 AppleTalk       Multicast       hardware filtering not important but
  11                                  avoid cards only doing promisc
  12 IP-Multicast    Multicast       hardware filters really help
  13 IP-MRoute       AllMulti        hardware filters are of no help

  59 PROMISC = This multicast mode is in fact promiscuous mode. Avoid using
  60 cards who go PROMISC on any multicast in a multicast kernel.
