Xen recently (changeset 16873:86c32269ba60) started looking for a
DHCP defaults file in /etc/sysconfig/dhcpd or /etc/defaults/dhcp.
Debian (lenny) puts this file in a different place though:
/etc/default/dhcp3-server. I added this location to Xen's search
path.

While wading through the patches made to Xen by OpenSUSE in their
[s]rpm, I found that they have removed various special casing for ifup
on ther distribution.

The ipv6-no-autoconf patch didn't disable IPv6 addrconf completely.
This means that the Xen bridge device still interfered with normal
IPv6 operation by engaging the IPv6 network with a bogus MAC address.
For details please refer to
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200360
The following patch completely disables IPv6 on the Xen bridge device
by temporarily setting the MTU to a value less than the minimum
allowed for IPv6.
Upstream will provide a cleaner way to disable IPv6 addrconf in
future, possibly in the form of a proc sysctl. Of course if the Xen
loopback device is removed it would render this change unnecessary.

This makes the script more idempotent if run twice (e.g. from hotplug and udev), since the second time the device will be taken down and not brought up again, leaving the host without networking.

This is done by defining ifup/down both to 'false' when they're
missing; then instead of attempting to parse the IP params from
the kernel command line, we get them from 'ip' instead. So this
works even with (for example) ip=dhcp on the kernel command line.
Also made a few minor syntax changes (in particular, replaced "=="
with "=", and ">&foo" with ">foo 2>foo") so this works with more
limited shells.

this aren't beautiful, but this gets the distro-specific code out of the body
of the network-bridge script and into a common place, while still preserving
the existing code behaviour.

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.
