f09428e472 zebra: fix broken evpn
To resolve link dependencies of unordered interfaces, the commit
`520ebf72b27c2462ce8b0dc5a1d4cb83956df69c` has separated assignment of
`zif->link_ifindex` and `zif->link` from `netlink_interface()` during startup.
The fixup stage of `zebra_if_update_all_links()` goes into the last of
`interface_lookup_netlink()`, it can't be executed in the case of error in
above `netlink_parse_info()`s.

`RTM_GETTUNNEL` is not supported in linux kernel until 5.18, so
`netlink_parse_info()` will throw error with the previous versions.

If two conditions are met, (it is a common case)
1. Interfaces are created before frr restart/start
2. Linux kernel version < 5.18

the link dependencies will not be done, then evpn feature will be broken.
IMO we should just ignore this error.

When using namespace VRF backend, and frr.conf contains:

FRR fails to start:

Fix this by returning CMD_WARNING rather than CMD_WARNING_CONFIG_FAILED

When redistributing connected addresses, the address family has
to be figured out. The calculation was not done, the next-hop
address length was not set, and as consequence, the nexthop

ipv4 addresses.

Calculate the family for connected addresses.

4cd690ae4d bgpd: add 'mpls bgp forwarding' to ease mpls vpn ebgp peering
RFC4364 describes peerings between multiple AS domains, to ease
the continuity of VPN services across multiple SPs. This commit
implements a sub-set of IETF option b) described in chapter 10 b.

The ASBR to ASBR approach is taken, with an EBGP peering between
the two routers. The EBGP peering must be directly connected to
the outgoing interface used. In those conditions, the next hop
is directly connected, and there is no need to have a transport
label to convey the VPN label. A new vty command is added on a
per interface basis:

This command if enabled, will permit to convey BGP VPN labels
without any transport labels (i.e. with implicit-null label).

restriction:
this command is used only for EBGP directly connected peerings.
Other use cases are not covered.

1bb550b63c bgpd: add resolution for l3vpn traffic over gre interfaces
When a route imported from l3vpn is analysed, the nexthop from default
VRF is looked up against a valid MPLS path. Generally, this is done on
backbones with a MPLS signalisation transport layer like LDP. Generally,
the BGP connection is multiple hops away. That scenario is already
working.

There is case where it is possible to run L3VPN over GRE interfaces, and
where there is no LSP path over that GRE interface: GRE is just here to
tunnel MPLS traffic. On that case, the nexthop given in the path does not
have MPLS path, but should be authorized to convey MPLS traffic provided
that the user permits it via a configuration command.

That commit introduces a new command that can be activated in route-map:
 > set l3vpn next-hop encapsulation gre

That command authorizes the nexthop tracking engine to accept paths that
o have a GRE interface as output, independently of the presence of an LSP
path or not.

A configuration example is given below. When bgp incoming vpnv4 updates
are received, the nexthop of NLRI is 192.168.0.2. Based on nexthop
tracking service from zebra, BGP knows that the output interface to reach
192.168.0.2 is r1-gre0. Because that interface is not MPLS based, but is
a GRE tunnel, then the update will be using that nexthop to be installed.

    interface r1-gre0
     ip address 192.168.0.1/24
    exit
    router bgp 65500

This is due to the way isisd is stopped: performing a "no router isis XXX"

isis_area_destroy() leaving many allocated memory unfreed.

This patch adds call to appropriate delete function or XFREE() when necessary to
properly free all alocated memory before terminating isisd.

zebra can change l2vni's tenant vrf with new `vid`, and then notify bgpd

Need to notify bgpd of the `vid` change.

default to vrf1, then check bgp's vni status.
