a linux configuration gives some explanation on how to set up an evpn
overlay in network namespaces.

this is used when parsing the newly network namespaces. actually, to
track the link of some interfaces like vxlan interfaces, both link index
and link nsid are necessary. if a vxlan interface is moved to a new
netns, the link information is in the default network namespace, then
LINK_NSID is the value of the netns by default in the new netns. That
value of the default netns in the new netns is not known, because the
system does not automatically assign an NSID of default network
namespace in the new netns. Now a new NSID of default netns, seen from
that new netns, is created. This permits to store at netns creation the
default netns relative value for further usage.
Because the default netns value is set from the new netns perspective,
it is not needed anymore to use the NETNSA_TARGET_NSID attribute only
available in recent kernels.

the walk routine is used by vxlan service to identify some contexts in
each specific network namespace, when vrf netns backend is used. that
walk mechanism is extended with some additional paramters to the walk
routine.

when duplicate address detection is observed, some incrementation,
some timing mechanisms need to be done. For that the main evpn
configuration is retrieved. Until now, the VRF that was storing the dad
config parameters was the same VRF that hosted the VXLAN interface. With
netns backend, this is not true, as the VXLAN interface is in the
same VRF as the bridge interface. The modification takes same definition
as in BGP, that is to say that there is a single bgp evpn instance, and
this is that instance that will give the correct config settings.

There can be cases where evpn traffic is not meshed across various
endpoints, but sent to a central pe. For this situation, add the
configuration knobs to force nexthop attribute. Upon that change,
nexthop unchanged attribute is automatically disabled.

this change is needed when a MAC/IP entry is learned by zebra, and the
entry happens to be in a different namespace. So that the entry be
active, the correct vni match has to be found.

PR #6376 introduced a VRF leafref in the frr-interface YANG module.
That change exposed a bug in the northbound layer that is causing
nhrpd to crash under certain circumstances. Even though nhrpd wasn't
converted to the new northbound model yet, make it implement the
frr-vrf module in order to work around this problem. This is a
temporary fix until a better solution is available.

The "set metric" command wasn't processing metric additions and
subtractions (using + and -) correctly. Fix those problems.
Also, remove the "+metric" and "-metric" options since they don't
work and don't make any sense (they could be interpreted as unitary
increments/decrements but that was never supported).

Modify bgpd.conf in all easily accessible topotests to use 3 10

In some cases one or both of the zlog targets in use here can be null,
we need to check for that.
Interestingly it appears we don't crash even when this is the case.
Undefined behavior ftw

Enhancement to update-delay configuration to allow setting globally
rather than per-instance. Setting the update-delay is allowed either
per-vrf or globally, but not both at the same time.
