On ifreload (down ops) we need to purge the cache entry of the bridge and its upper devices
to avoid stale values in our cache.
ifup this config, then remove bridge-vids 20, ifreload: since the bridge is removed because
of ifreload_down_changed=1, we need torecreate the vlan bridge.10 and it's configuration, the
cache is stale. We need to clear it to remove the ip 10.10.10.10/32.

New VRRP macvlan devices should be set into protodown when first
created, to prevent ND traffic and other automatically generated kernel
traffic from being transmitted on the interface and causing downstream
MAC moves.

To work on ifupdown2 i'm using Pycharm on macOS. ifupdown2 runs in a
debian VM. To use Pycharm remote execution capabilities, we need several
symlinks (one per command). Git needs to ignore those symlinks :)

For each VRRP configuration we create 2 macvlans (ip4 and ip6), if the ip4
is removed from the config we need to remove the associated macvlan (same
for ip6).
Testing Done: remove all ip4 (or ip6) from vrr attribute line

if igmp snooping is enabled on a vxlan bridge and if the
vxlan_bridge_igmp_snooping_enable_port_mcrouter is turned on, ifupdown2
will automatically enable multicast router on the vxlan brport unless
this attribute was provided by the user. The policy is enabled by default.
The policy can be disabled as follow:
{
"bridge": {
"module_globals": {
"vxlan_bridge_igmp_snooping_enable_port_mcrouter": "no"
}
}
}
auto br0
iface br0
bridge-ports vx42

ifupdown2 behaviour significantly diverges from ifupdown on debian stretch.
Original ifupdown uses run-parts which supposedly doesn't run non-executable
files in the directory. However, ifupdown2 doesn't seem to make this
distinction.
This patch will log warning EACCES exceptions (instead of log error) and exit 0

ifupdown2 used /var/tmp/network/ to store its state file
upstream users reported that when /var/tmp is not mounted
before network configuration ifupdown2 fails. We now let
user define which location they want to use for the state
file.

some of those release were available but under a different name so
technically those version numbers were never released.

The new code base supports installation via pypi so we need to update the
imports statement.
It's also good practice to use the existing IO apis to read/write and execute
sub-commands, those API will do error handling and logging.

batman wasn't in master-next so it got removed during the last merge
this commit adds it back to master.
See PR #12
From Maximilian Wilhelm:
This commit adds support for configuring B.A.T.M.A.N. advanced interfaces
with ifupdown2. B.A.T.M.A.N. advanced is a protocol to build Layer2 based
mesh networks with. It's supported in the Linux kernel and thus available
in many Linux environments.
A configuration could look like this
auto bat0
iface bat0
batman-ifaces eth1 eth2.23
batman-ifaces-ignore-regex .*_nodes
batman-hop-penalty 23
#
address 192.0.2.42/24
where »bat0« would be the local connection to the mesh network.
The interfaces »eth1« and »eth2.23« would be used by the B.A.T.M.A.N. adv.
protocol to communicate to other member of the mesh network.
Any interfaces matching the »ifaces-ignore-regex« will be gently ignored
by ifquery and ifreload as there might be some tunnels or interfaces
added to the mesh network by other means which should not be removed by
any subsequent ifreload run.
The »hop-penalty» parameter set the penalty of this node within the mesh
network.

ifupdown2 (1.2.2) unstable; urgency=medium
* Support for new iproute2 format (bridge vlan show)
* Pypi install: local addons modules should be loaded first
* Fix: link-down yes on vrf slaves
* Fix: nlmanager: use strerror to format kernel error
* Add: new checks for existing device with vxlan attributes
* Ethtool: FEC: translate None and NotSupported values to link-fec off

ifupdown2 can be installed via apt/dpkg or via pypi (pip), those two installation methods have
two different installation directory. Our main installation dir is /usr/share/ifupdown2. This is
also were other scripts might add their own addon.
If ifupdown2 is installed via pypi we need to make sure we are loading the script-added addon modules

A newer iproute2 version changed the bridge vlan show output, ifupdown2 relies
on the previous format, we have the convert data into old format:
