6# Script for configuring a vif in routed mode.
7# The hotplugging system will call this script if it is specified either in
8# the device configuration given to Xend, or the default Xend configuration
9# in /etc/xen/xend-config.sxp.  If the script is specified in neither of those
10# places, then vif-bridge is the default.
11#
12# Usage:
13# vif-route (add|remove|online|offline)
14#
15# Environment vars:
16# vif         vif interface name (required).
17# XENBUS_PATH path to this device's details in the XenStore (required).
18# Read from the store:
19# ip      list of IP networks for the vif, space-separated (default given in
20#         this script).
21#
22# This script will set up proxy arp  for any ip addresses that are being routed
23# type read to determine if the device is ioemu
