Command 'show ip route vrf <vrf_name> json' returns a valid json object,
however if instead of <vrf_name> we specify 'all', we get an invalid json
object, like:
{//vrf1 routes}{//vrf2 routes}{vrf3 routes}
After the fix:
{"vrf1":{//vrf1 routes},"vrf2:{//vrf2 routes},"vrf3":{//vrf3 routes}}
Which is a valid json object, that can be parsed effectively using built-in
modules. The rest of the commands remains unaffected and behave the same.

Currently, json output of show ip route command are no pretty format.
This is an extremely expensive operation at high scale
(with high number of routes with many paths).
Zebra json non-pretty command support added:

The default vrf is generally non-NULL, except when shutdown. So, most
of the time it is not necessary to check if it is NULL, we should
remove the useless checks for it.

Use the already existing mpls label code to store VNI
info for vxlan. VNI's are defined as labels just like mpls,
we should be using the same code for both.
This patch is the first part of that. Next we will need to
abstract the label code to not be so mpls specific. Currently
in this, we are just treating VXLAN as a label type and storing
it that way.

This patch addresses following bug fixes
- Fix vtysh doc string in "show evpn access-vlan..." command
- Multicast group handling was little complex. This change avoids calling
multiple functions and directly calls the zebra_vxlan_if_update_vni for
mcast group updates.
- When a vlan-vni map is removed, the removed vni deletion was happening
in FRR with SVD config. This was resulting in stale vni and not
resulting propagation of the vni deletion.
During vni cleanup (zebra_vxlan_if_vni_clean) zebra_vxlan_if_vni_del
was called for vni delete which is not correct. We should be calling
zebra_vxlan_if_vni_entry_del for the given vni entry.

Multiple vlan aware bridge data structure changes and its corresponding bridge
handling changes.
A new vlan-table is maintained for each bridge which records the zebra_l2_bridge_vlan
entry. zebra_l2_bridge_vlan maps vlan to access_bd associated to this bridge.
Existing zebra_evpn_access_bd structure is vlan aware which is now modified to be
(vlan, bridge) aware.
Whenever a new access_bd is instantiated, a corresponding entry is also recorded
in the zebra l2 bridge for the vlan.
When the access_bd is dereferenced or whenever a bridge is deleted, the
association is cleaned up.

JSON object in sync with "nexthops" JSON object of

Volta submitted notification changes for the dplane that had a
special use case for their system. Volta is no more, the code
is not being actively developed and from talking with ex-Volta
employees there is no current plans to even maintain this code.
Wrap the special handling of nexthops that their asic-dataplane
did in a bit of code to isolate it and allow for future removal,
as that I do not actually believe anyone else is using this code.
Add a CPP_NOTICE several years into the future that will tell us
to remove the code. If someone starts using it then they will
have to notice this variable to set it and hopefully they will
see my CPP_NOTICE to come talk to us. If this is being used then
we can just remove this wrapper.

FRR does not use the NLM_F_APPEND semantics ( in fact I would argue that
the NLM_F_APPEND semantics just introduce pain for all parties involved )
I would also argue that most people who use the kernel netlink api
have recognized that NLM_F_APPEND for a route is a recipe for disaster
that is well documented and as such it is not used as anything other
than a curiousity by operators.
See:
https://bugzilla.redhat.com/show_bug.cgi?id=1337855https://github.com/thom311/libnl/issues/226
Are 2 great examples of how confusing it is for anyone in user
space to know what the correct thing to do is. Given that
new fields can be added with no semantics to allow us to know
what has resulted in a change or not.
In an attempt to recognize this, let's note that FRR
believes it has gotten out of sync with the kernel.
Future commits will react to the desynchronized route
and request from the kernel a reload of that specific
route if possible.
