code into vif-common.sh. Fix the antispoofing in network-bridge to allow forwarding from physical device to bridge, and vif0.0 to eth0. Change the interface between netback driver and vif hotplugging scripts. The mac address and bridge details are read from the store directly by the script, so that the kernel driver does not need to get involved. Remove an awful lot of cruft from vif-bridge. Move the iptables handling into vif-common.sh, and fix it so that the new vif can get past the antispoofing entries. Merge vif-nat and vif-route into this structure too. Use ip instead of ifconfig to get necessary details. Signed-off-by: Ewan Mellor <ewan@xensource.com>

# Script for configuring a vif in routed mode.

# The hotplugging system will call this script if it is specified either in
|
|
# the device configuration given to Xend, or the default Xend configuration
|
|
# in /etc/xen/xend-config.sxp. If the script is specified in neither of those
|
|
# places, then vif-bridge is the default.

# Usage:

# vif-route (up|down)

#
|
|
# Environment vars:

|
# vif vif interface name (required).

|
# XENBUS_PATH path to this device's details in the XenStore (required).

# Read from the store:
