Akihiro Motoki 486962d0e2 nec plugin: Compare OFS datapath_id as hex int
Previously NEC plugin compares old and new datapath_ids as
a string and zero padding in hex notation is not taken into
account when compared. This causes unintended deletion and
recreation of a port on OpenFlow controller. This patch fixes
this issue by comparing datapath_ids as hex int.
