6913cb1b20 zebra: Don't resolve to diff interface if given
If the nexthop is of type `GATEWAY_IFINDEX` then the nexthop
should not resolve to a nexthop that has a different ifindex
from the one given.

478566d68b zebra: avoid using zebra datastructs in evpn dataplane path
Some netlink-facing code used for evpn/vxlan programming was
being run in the dataplane pthread, but accessing zebra core
datastructs. Move some additional data into the dataplane
context, and use it in the netlink path instead.

fd267f0808 zebra: Correct /32 addr del with broadcast set
Since we are now away from the dual use of the destination field, there
is no need to single out /32 addresses as broadcast. This was bugged
anyway, since the same /32 criteria was used for IPv6 addresses as well,
when `connected_check_ptp` is called in `connected_delete_ipv6`.

79becec8ac zebra : zebra redistributing IPV4 link local Addresses inconsistently.
Create an interface with IP4 link local address 169.254.0.131/25.
In BGP enable the redistribute connected. Now Zebra will not send
the route corresponding to IPV4 link local address. Now made this
interface down and up. Zebra sends the route to BGP.
Zebra should not send this route to BGP.
This Fix would make the behaviour consistent and would not send the
routes corresponding to IPV4 Link local addresses.

ea7ec26162 zebra: Ensure master's ifname is known, even if slave comes up first
In if_netlink.c, when an interface structure, ifp, is first created,
its possible for the master to come up after the slave interface does.
This means, the slave interface has no way to display the master's ifname
in show outputs. To fix this, we need to allow creation by ifindex instead
of by ifname so that this issue is handled.

We used the vrf_id in the rtm_table field of the netlink rtmsg to fetch L3VNI.
But, now we program table_id to rtm_table field instead of vrf_id.

Instead, use nexthop->vrf_id to fetch the L3VNI.
