Issue:
Client---LHR---RP
1. Add kernel route for RP on LHR. Client send join
2. (*,G) will be get created in LHR and RP.
3. Kill the FRR on all the nodes
4. Start FRR only on LHR node
5. In LHR, (*, G) will be created with iif as unknown.
Root cause:
In the step 4, When LHR will receive igmp join, it will call
the function pim_ecmp_fib_lookup_if_vif_index which will look
for nexthop to RP with neighbor needed as false. So RPF lookup will
be true as the route is present in the kernel. It will create a
(*, G) channel_oil with incoming interface as the RPF interface
towards RP and install the (*,G) mroute in kernel.
Along with this (*,G) upstream gets craeted, which call the function
pim_rpf_update, which will look for the nexthop to RP with neighbor
needed as true. As the frr is not running in RP, no neighbor is present
on the nexthop interface. Due to which this will fail and will update
the channel_oil incoming interface as MAXVIFS(32).
Fix:
pim_ecmp_fib_lookup_if_vif_index() call the function pim_ecmp_nexthop_lookup
with neighbor_needed as true.

Issue: REGISTER-STOP Rx is always displaying 0.
Root-cause: pim_ifstat_reg_stop_recv is not getting
incremented when register stop message is received.
Fix: Increment pim_ifstat_reg_stop_recv on receiving
of pim register stop packet.

The lif variable was being set in the if statement and
immediately copied into from xf. No need to do this

The handlers for a couple of the main LSP-oriented zapi
messages explicitly limited themselves to a single out-label.
Allow multiple labels if the sender ... sends them.

We made the decision to explicitly trust kernel and system routes
of every other type with 058c16b7e2.
So, we should trust directly connected routes the same way, assuming
the interface exists.
Old Behavior:
K 2.2.2.1/32 [0/0] is directly connected, unknown inactive, 00:00:39
New Behavior:
K>* 2.2.2.1/32 [0/0] is directly connected, test1, 00:00:03
As a bonus, this fixes the issues we were seeing with not removing
directly connected routes of certain interface types when
those interfaces go down/are deleted.

We already have a generic support for add/sub in route-maps. It's already
handled in route_value_compile().
Just convert to string (allow passing (-) minus sign) - works like expected.

SA has found a case where we did a table lookup of a rn( and
associated lock of that node ) where we did not unlock it.
Unlock the node before moving on to the next one.

This directive was undocumented, but is the way to configure the
next-hop to be left unchanged for ipv6 setups (in ipv4, a route-map with
`set next-hop unchanged` works fine, but this is unavailable for ipv6) .

Implement the [no] version of `pbr table range`. We had the command
but were doing nothing with it.
This just calls the set_table_range API again using the defaults.

When a client connects to zebra with GR capabilities and
then restarts, it might disconnect again even before hello is
sent leading zebra cores.
GR should be supported only for dynamic neighbor who are capable
of restarting.
