Need this as commit cf34df857273d3be289e00590d80498cc11149ee broke
the plugin.

Changes from the above:
1. The delete network is removed from withing a transaction
2. dynamic extension are treated outside of the port create
   transaction

In addition to this commit 4f4d9ad3d33da85df2530347617b9dbc33543e54
broke us.
