For nexthop handling use the actual resolved nexthop.
Nexthops are stored as a `special` list:
Suppose we have 3 way ecmp A, B, C:
nhop A -> resolves to nhop D
|
nhop B
|
nhop C -> resolves to nhop E
A and C are typically NEXTHOP_TYPE_IPV4( or 6 ) if they recursively resolve
We do not necessarily store the ifindex that this resolves to.
Current nexthop code only loops over A,B and C and uses those for
the zebra_rnh.c handling. So interested parties might receive non-fully
resolved nexthops( and they assume they are! ).
Let's convert the looping to go over all nexthops and only deal with
the resolved ones, so we will look at and use D,B and E.

A recent commit broke this functionality, so add a very basic
route leak vrf test.
router bgp 99 vrf DONNA
address-family ipv4 uni
redistribute connected
import vrf EVA
router bgp 99 vrf EVA
address-family ipv4 uni
redistribute connected
import vrf DONNA
Routes should be leaked between the two vrf's. Ensure that it does.

We have set up automated builds for the topotest images at dockerhub.
Therefore, people don't need to perform a local build to run the
topotests on docker, but can use the image built by dockerhub.
As there is not much benefit in building locally, but the disadvantage
of weird errors if using an outdated image, change the topotests target
to always pull the most recent image from dockerhub.
Add an environment variable to disable this, e.g. for local development.

YANG allows lists without keys for operational data, in which case
the list elements are uniquely identified using a positional index
(starting from one).
This commit does the following:
* Remove the need to implement the 'get_keys' and 'lookup_entry'
callbacks for keyless lists.
* Extend nb_oper_data_iter_list() so that it special-cases keyless
lists appropriately. Since both the CLI and the sysrepo plugin
use nb_oper_data_iterate() to fetch operational data, both these
northbound clients automatically gain the ability to understand
keyless lists without additional changes.
* Extend the confd plugin to special-case keyless lists as well. This
was a bit painful to implement given ConfD's clumsy API, but
keyless lists should work ok now.
* Update the "test_oper_data" unit test to test keyless YANG lists in
addition to regular lists.

During L3VNI add delete, configured non-default
route-target is not replayed correctly.
Non-default route-target should only be deleted
during unconfiguring under bgp vrf instance,
during delete of l3vni only unmap from the VRF.
during addition of l3vni map back to the VRF
Ticket:CM-21482
Testing Done:
Bring up evpn configuration with L3vni up with
non-default route-target.
Perform delete/add of L3vni and validated non-default
route-target is mapped back to vrf.

Finding an LSP by its id is useful not only for the
`show isis database` command.
So move it out into its own function to make it reusable.

We should really populate the neighbor list for the flooding
optimization from our local adjacency database and not from
a one-hop SPF.
If we use SPF, we may end up never exchanging information with
some neighbors since the bidirectional connection check for spf
fails, since LSPs did not get exchanged.

If CFLAGS contains something like `-fdebug-prefix-map=/build/path=.`, we
need to remove it from CONFIG_ARGS so it doesn't get baked into `show
version`. Otherwise, build becomes non-reproducible if the build path
changes. To avoid other things creeping in, let's just remove *FLAGS in
their entirety. (Not really reliable information anyway.)
With this commit, FRR build should be 100% reproducible.

ConfD and Sysrepo implement configuration transactions using a
two-phase commit protocol (prepare + abort/apply). For network-wide
transactions to work, ConfD and Sysrepo move to the second phase of
the commit protocol only after receiving the results of the first
phase from all devices involved in the transaction. If all devices
succeed in the 'prepare' phase, then all of them move to the 'apply'
phase and the transaction is committed. On the other hand, if any
device fails in the 'prepare' phase, all of them move to 'abort'
phase and the transaction is aborted.
The confd and sysrepo plugins were implementing the full
two-phase commit protocol upon receiving a request to validate
the configuration changes and allocate all resources required to
apply them (first phase). The notifications to abort or apply the
changes (second phase) were being ignored since everything was being
done in the first phase for simplicity. This wasn't a problem for
single-device transactions, but it is for transactions involving
multiple devices. Rework the code a bit to do things properly and
fix this problem.

The "show" command will be available in the configuration mode and
all configuration subnodes. It's used to display the section of
the candidate configuration being edited, instead of displaying
the entire candidate configuration like when "show configuration
candidate" is used. The goal is to add more convenience when editing
huge configurations.
When the transactional CLI mode is not used, the candidate
configuration and the running configuration are identical, hence in
this case we can say that the "show" command displays the section
of the running configuration being edited.
Example:
ripd(config)# show
Configuration:
!
frr version 6.1-dev
frr defaults traditional
!
interface eth0
ip rip split-horizon poisoned-reverse
ip rip authentication mode md5
ip rip authentication string supersecret
!
interface eth1
ip rip receive version 1
ip rip send version 1
!
router rip
allow-ecmp
route 10.0.1.0/24
route 10.0.2.0/24
!
end
ripd(config)#
ripd(config)#
ripd(config)# interface eth0
ripd(config-if)# show
!
interface eth0
ip rip split-horizon poisoned-reverse
ip rip authentication mode md5
ip rip authentication string supersecret
!
ripd(config-if)# exit
ripd(config)#
ripd(config)#
ripd(config)# router rip
ripd(config-router)# show
!
router rip
allow-ecmp
route 10.0.1.0/24
route 10.0.2.0/24

ripd(config-router)#
The "show" command only works for daemons converted to the new
northbound model. vtysh support will be implemented at a later
time as it will require some level of coordination between vtysh
and the FRR daemons.
