adae8192d1 zebra: EVPN check vxlan oper up in vlan mapping
When VLAN-VNI mapping is updated, do not set the L2VNI up event
if the associated VXLAN device is not up.
This may result in bgp synced remote routes to skip installing
in Zebra and onwards (Kernel).

cb6f7b153e lib, zebra: Do not have duplicate memory type problems
In zebra_mpls.c it has a usage of MTYPE_NH_LABEL which is
defined in both lib/nexthop.c and zebra/zebra_mpls.c.  The
usage in zebra_mpls.c is a realloc.  This leads to a crash:

Clearly replacing a label stack is an operation that should be owned by
lib/nexthop.c.  So lets move this function into there and have
zebra_mpls.c just call the function to replace the label stack.

f51d2a6b97 zebra: Don't display the vrf if not using namespace based vrfs
Currently when doing a `show ip route table XXXX`, zebra is displaying
the current default vrf as the vrf we are in.  We are displaying a
table not a vrf.  This is only true if you are not using namespace
based vrf's, so modify the output to display accordingly.

Currently zebra starts the graceful restart timer as well as
allows connections from clients before all data is read in
from the kernel as well as the possiblity of allowing client
connections before this happens as well.

Let's move the graceful restart timer start till after this is
done as well as not allowing client connections till then as well.

Piped through specifying the safi through the import table functions
rather than hardcoding to SAFI_UNICAST.
Import still only import routes from the URIB subtable, only added the

Currently the mroute code was not allowing the mroute
to be sent to the dataplane.  This leaves us with a
situation where the routes being installed where never
being set as installed and additionally nht against
the mrib would not work if the route came into existence
after the nexthop tracking was asked for.

Turns out all the pieces where there to let this work.
Modify the code to pass it to the dplane and to send
it back up as having worked.

96192f6aee zebra: drop NEWLINK event handling in the main thread
NEWLINK is only registered by the dplane thread, the main thread
doesn't care about it. So remove the real process of `netlink_link_change()`
for NEWLINK event in main thread.

And move NEWLINK/DELLINK event to the block where the dplane messages
are kept together.

6cdc82b21b zebra: fix showing nexthop vrf for ipv6 blackhole
For some reasons the Linux kernel associates the ipv6 blackhole of non
default table the lo interface.

> root@r1# ip -6 route show table 100
> root@r1# ip -6 route add unreachable default metric 4278198272 table 100
> root@r1# ip -6 route show table 100
> unreachable default dev lo metric 4278198272 pref medium

As a consequence, the VRF default that owns the lo interface is shown as
the nexthop VRF:

> r1# show ipv6 route table 20
> Table 20:
> K>* ::/0 [255/8192] unreachable (ICMP unreachable) (vrf default), 00:18:12

Do not display the nexthop VRF of a blackhole. It does not make sense
for a blackhole and it was not displayed in the past.
