Openvswitch already manage mtu if ovs-mtu is defined.
(Ovs manage mtu in userland, and sync mtu for some interfaces in kernel).
If mtu is changed by address module, before the ovs userland mtu,
this give packets drop.

Add option 'veth-peer-name' to veth links and ensure proper configuration.
The option »veth-peer-name« forces an veth peer link to be created with
a specific interface name. As the interface name of the "local" part of
the veth link pair already is defined by the name of the interface stanza
this option is added to, now both sides are clearly named.
As there is a bidirectional dependency of both link pairs - both cannot
exist without the other - this presents a problem when setting up all
interfaces. Depending on which interface is set up first there might be
a problem when only on dependency is specified. Therefore adding the
»veth-peer-name« option to both interface of the veth link pair ensures
that regardless of which side is configured first the peer name will be
set correctly. This intentionally creates a circular dependency which is
handled accordingly.
Fixing the config check for veth link-type while at it :)

Enabling this attribute on a bridge will
enslave a dummy interface to the bridge
example:
auto bridge
iface bridge
bridge-vlan-aware yes
bridge-always-up yes

ifupdown2 now tries to monitor the dhclient call to see if an ip address was
successfully assigned on the requested device. The number of retry can be
customized using the "dhclient_retry_on_failure" policy variable (which defaults to 0)
This commit also add debugging capabilities by automatically enabling sysloging when
configuring dhcp at boot (with PERFMODE option).

Seems like the regex module might be behave a little bit different in python3.
The regexes used to validate l2protocol-tunnel were returning incorrect lists:
value=lldp,stp
regex=['', 'l', 'l', 'd', 'p', '', 's', 't', 'p', '']
the patch simplifies the code by using str.translate and str.split

In the addressvirtual module we have some code that checks if stale macvlans should
be deleted (when the address-virtual or vrrp keywords are removed from the config).
To find those stale macvlans we basically do a glob search in /sys/class/net/ with
the macvlan prefix (ifname) defined by ifupdown2: '%s-v' % ifaceobj.name[0:13], which
for a device foo would create macvlans named foo-v0...foo-vN.
In this particular case we have a vxlan named: sha3szx4-vpn, which gets matched
and removed without actually checking if this device is a macvlan or not.
This commit adds a link_kind check to ensure that we are only removing macvlans.

ES bonds have the same "init state" requirements as CLAG bonds -
1. A bond needs to be designated as an "es-bond" for this purpose.
For clag-bonds we used "clag-id" attr (to designate a bond as a "clag-bond").
For ES bonds we will use "es-sys-mac" attr.
2. Slaves added to an "ES bond" must have protodown-on.
This is again similar to CLAG bonds
3. And vice-versa i.e. when a slave is removed from an "es-bond",
protodown-on must be cleared.
4. When es-sys-mac is first set on a bond, all the bond-slaves must be
placed in "protodown-on" state. This is needed whether FRR is running at that point or not.

When --with-defaults is provided we update the stanza-data structure without
making sure we are dealing with a vxlan intf.

nlmanager: ipnetwork: fix 'IPv4Address' object has no attribute 'split' exception
nlpacket: use IP[v4|6]Address object when network mask is not provided or needed
nlpacket: AttributeIPAddress: fix decode handler for Routes
During the python2 to 3 migration there was some refactoring
Seems like some code specific to Route-decoding was removed
This patch is fixing the issue by re-adding this code and
tweaking it a little bit (to make it nice and clean :))

this feature doesn't seem to be working anyway. This can be revisited in the
future but this allows us to drop the python3-argcomplete dependency for now

Python3 sets are using the python hash seed to generate random hashes
which makes the sets ordering different everytime. In our case we need
to honor the user configuration (first device should be enslaved first)
