10# Script for configuring a vif in routed mode.
11# The hotplugging system will call this script if it is specified either in
12# the device configuration given to Xend, or the default Xend configuration
13# in /etc/xen/xend-config.sxp.  If the script is specified in neither of those
14# places, then vif-bridge is the default.
15#
16# Usage:
17# vif-route (add|remove|online|offline)
18#
19# Environment vars:
20# vif         vif interface name (required).
21# XENBUS_PATH path to this device's details in the XenStore (required).
22# Read from the store:
23# ip      list of IP networks for the vif, space-separated (default given in
24#         this script).
25# V6PREFIX  prefix of v6 address to use
26# Note that the v6 support is kind of broken because there's not really a way to populate the v6 prefix
27# This script will set up proxy arp  for any ip addresses that are being routed
28# type read to determine if the device is ioemu
