/* Create and configure a Platform Event Trap handler for the given
 * channel in the given domain.  Parameters are: 
 *
 *  channel - The specific channel to configure.  There is not real
 *      way to know all the channels and what IP addresses should
 *      be used for each.
 *  ip_addr - The IP address to tell the PET to send messages to, if
 *      applicable for this domain.
 *  mac_addr - The MAC address to tell the PET to send messages to,
 *      if applicable for this domain.
 *  eft_sel - the Event Filter selector to use for this PET destination.
 *      Note that this does *not* need to be unique for different OpenIPMI
 *      instances that are using the same channel, since the configuration
 *      will be exactly the same for all EFT entries using the same
 *      channel, assuming they share the same policy number.
 *  policy_num - The policy number to use for the alert policy.  This
 *      should be the same for all users of a domain.
 *  apt_sel - The Alert Policy selector to use for this PET destination.
 *      Note that as eft_sel, this needs to be unique for each different
 *      OpenIPMI instance on the same channel, as it specifies the
 *      destination to use.
 *  lan_dest_sel - The LAN configuration destination selector for this PET
 *      destination.  Unlike eft_sel and apt_sel, this *must* be unique
 *      for each OpenIPMI instance on the same channel.
 *
 * Creating one of these in a domain will cause event traps to be received
 * and handled as standard events in OpenIPMI.
 *
 * Note that this uses the standard SNMP trap port (162), so you
 * cannot run SNMP software that receives traps and an IPMI PET at
 * the same time on the same machine.
