Currently, the only way to enable arp-accept is to enable
a policy with l3_intf_arp_accept.
But this enable arp-accept for all bridges.
This option allow to define it for specific bridge.
This is needed with bgp-evpn and vm migration
https://github.com/FRRouting/frr/issues/4904
The bridge-ports-condone-regex option can be used to tell ifupdown2 to let
some bridge member ports alone and do not remove them on ifreload runs.
This might come in handy when running a KVM (or any other virtualization
system) host with a bridged network setup.
Before this option, ifupdown2 would either complain about not existing
member ports when setting up the bridge (if all VM interfaces were to
be specified in /etc/network/interfaces) or remove any VM interface
from a bridge if it was not specified in /e/n/i.

Add a ifupdown2 policy attribute dhcp6-duid to allow user to specify the DUID type
to be used on an IPv6 enabled interface.

Not when we are reloading and applying config ot existing macvlans -
somebody may be using them, we don't want to protodown them in that
case.

It is available since Kernel 4.19 and has two parmeters:
1. XFRM ID to map to an SA/SAs
2. Underlying Interface if you want to take advantage of IPSec Hardware Offload
Otherwise it is treated as a normal interface and not like a tunnel (VTI).
I added two attributes to the interface to configure it and otherwise use it as a normal interface.
One example is:
auto ipsec1
iface ipsec1 inet
xfrm-physdev lo
xfrmid 1
Add a new attribute for B.A.T.M.A.N. advanced interfaces to control the
B.A.T.M.A.N. advanced routing algorithm to be used when setting up new
interfaces. As the routing algorithm must be set before an interface is
created, it needs special handling and can't be implemented as a common
attribute. D'oh.

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.

Now we support the following config:
auto swp1
iface swp1
vrrp 3 50.0.1.1/24

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
bridge-mcsnoop yes
auto vx42
iface vx42
vxlan-id 42
$ ifreload -ad
will show that the config is applied
