- Package `ndpd.conf` in the switch zone with defaults that preclude DHCPv6 on any interface. - After fetching the correct, stable MAC addresses from the switch SP, `dpd` now uses the base MAC to write out a DUID to a file where illumos's `dhpcagent` can pick it up and use it later in exchanges. It then starts DHCP on that interface, after ensuring a link-local IPv6 address derived from that MAC address exists as well. - Some misc cleanup, logging improvements, `IdOrdMap` over `BTreeMap`

ndpd.confin the switch zone with defaults that preclude DHCPv6 on any interface.dpdnow uses the base MAC to write out a DUID to a file where illumos'sdhpcagentcan pick it up and use it later in exchanges.tfportdnow creates both a link-local address and allows DHCPv6 to run on the interface as well. This should triggerdhcpagent, which would pick up the stable DUID from the previous item.IdOrdMapoverBTreeMap
