From 56b0029014ff7e844c2fde45f7b52b7f115757e8 Mon Sep 17 00:00:00 2001 From: Darragh O'Reilly Date: Mon, 17 Nov 2014 10:20:58 +0000 Subject: [PATCH] linuxbridge-agent: make vxlan unicast check more efficent A list with the full range of vxlan VNIs (1 to 2**24) was using over 300MB of memory. This patch uses xrange instead of range.
