lan_del_multi(9r)
NAME
  lan_del_multi - Network: Deletes a multicast address from the multicast
  table

SYNOPSIS
  int lan_del_multi(
	  struct lan_multi *lmt,
	  unsigned char *maddr );

ARGUMENTS
  lmt Specifies a pointer to the multicast table.

  maddr
      Specifies a pointer to the multicast address to be deleted.

DESCRIPTION
  The lan_del_multi interface deletes a multicast address from the multicast
  table. If the reference count to the address is greater than one,
  lan_del_multi decrements the reference count but does not delete the
  address. If the reference count is one, lan_del_multi decrements the
  reference count and removes the address.

  The device driver should check the return value from lan_del_multi to
  determine whether the multicast table changed as a result of the operation.
  If so, it should update the hardware.

RETURN VALUES
  On successful completion, the lan_del_multi interface returns one of the
  following values:

  LAN_MULTI_FAIL
      Indicates that the operation failed.

  LAN_MULTI_NOT_CHANGED
      Indicates that the reference count was decremented but the multicast
      address was not deleted.

  LAN_MULTI_CHANGED
      Indicates that the address was removed from the multicast table; the
      driver should update the hardware.
