From 61b43f134f6bd36403a1da14d03548cc4e94fdc9 Mon Sep 17 00:00:00 2001 From: Ryan Brown Date: Mon, 12 Sep 2016 18:26:13 -0400 Subject: Handle EC2 instances with multiple network interfaces (#4766) Currently instances with multiple ENI's can't be started or stopped because sourceDestCheck is a per-interface attribute, but we use the boto global access to it (which only works when there's a single ENI). This patch handles multiple ENI's and applies the sourcedestcheck across all interfaces the same way.
