+# All the work is done here in the "end:" tag. There are four possible cases:
+#
+# 1) A new node and possibly sub-tree with hwaddr has been created
+# 2) Value of hwaddr node in sub-tree has been changed
+# 3) The hwaddr node in sub-tree has been deleted
+# 4) This node (and hence entire sub-tree) has been deleted
+#
+# The flow is the same in all cases. First, we delete any
+# previous static ARP translation that may be in place for this
+# IP addr. This will typically fail in case (1) and in case (4) if the
+# hwaddr node had been previously deleted. Then, if a hwaddr is defined,
+# we add a new startic ARP translation for this IP addr pointing to that
+# hwaddr. This should always succeed, so we don't try to hide error
+# messages from the user.
+#
+# We always force a successful return in order to prevent transient
+# failures of the "arp" command from failing the commit.
