From 2feaffcb4af8e311b56328015bcfd82f5b15626c Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Sat, 14 Jan 2017 10:30:50 -0500 Subject: Provision linux stack ip4 and ip6 addresses for tap interfaces To simplify system configuration. Converted existing code to use an argument structure, instead of [one or two too many] discrete parameters.
