Document the `sleep` statement so people know that we are sleeping
because we are waiting for the BFD down notification. If we don't
sleep here it is possible that we get outdated `show` command results.

Call the `show` commands less often to reduce the CPU pressure.
Also increase the wait time from 60 to 80 seconds to have spare room
for failures (4 times more). This is the latest measure wait time:

Reduce timers so we send hello packets more often and reduce dead
interval to converge faster.
Previous test wait amount:
> INFO: topolog: 'router_json_cmp' succeeded after 47.20 seconds
New test wait amount:
> INFO: topolog: 'router_json_cmp' succeeded after 20.08 seconds

Currently, it is possible to configure IPv6 protocols for IPv4
redistribution and vice versa in CLI. The YANG model doesn't allow this
so the user receives the following error:
```
nfware(config-router)# redistribute ipv4 ospf6 level-1
% Failed to edit configuration.
YANG error(s):
Invalid enumeration value "ospf6".
Invalid enumeration value "ospf6".
Invalid enumeration value "ospf6".
YANG path: Schema location /frr-isisd:isis/instance/redistribute/ipv4/protocol.
```
Let's make CLI more user-friendly and allow only supported protocols in
redistribution commands.

`yang_dnode_get` will `assert` if no YANG node/model exist, so lets test for
its existence first before trying to access it.
This `assert` is only acceptable for internal FRR usage otherwise we
might miss typos or unmatching YANG models nodes/leaves. For gRPC usage
we should let users attempt to use non existing models without
`assert`ing.

Description:
When grace lsa received, DUT is adding
the copy of the lsas to all nbrs retransmission list as part of
flooding procedure and subsequently incrementing the rmt counter in
the original the LSA. This counter is supposed to be decremented
when ack is received by nbr and the lsa will be removed from retransmission list.
But in our current scenario,
Step-1:
When GR helper is disabled, if DUT receives the grace lsa
it adds the lsa copy to nbrs retransmission list but original
LSA will be discarded since GR helper disabled.
Step-2:
GR helper enabled and DUT receives the grace lsa, as part
of flooding process all nbrs have same copy of lsa in their
corresponding rmt list which was added in step -1 due to this
the corresponding rmt counter in the original lsa is not getting
incremented.
Step-3:
If the same copy of the grace lsa received by DUT, It considers
as implicit ack from nbr if the same copy of the lsa exits in its
rmt list and subsequently decrement the rmt counter.
Since counter is zero (because of step-1 and 2) , it is asserting while decrement.

The lsa->expire thread is for keeping track of when we
are expecting to expire(remove/delete) a lsa. There
are situations where we just decide to straight up
delete the lsa, but we are not ensuring that the
lsa is not already setup for expiration.
In that case just stop the expiry thread and
do the deletion.
Additionally there was a case where ospf6d was
just dropping the fact that a thread was already
scheduled for expiration. In that case we
should just setup the timer again and it will
reset it appropriately.

With v6 interface based peering, we send the global as well as the LL address
as nexthops to the peer. When either of these were removed on the interface
we were not necessarily resetting the connection. Leaving bgp in a state
where the peer had reachability for addresses that are no longer in use.
Modify the code that when we receive an interface address deletion
event. Check to see that we are using the v6 address as nexthops
for that peer and if so, tell it to reset.
I initially struggled with a hard reset of the peer or a clear but
choose to follow other places in the code that we noticed address
changes that resulted in hard resets.

Problem Statement:
==================
pim maintains two counters hello tx and hello rx at interface level.
At present pim needs to send the hello message prior to other pim
message as per RFC. This logic is getting derived from the tx hello
counters. So when a new neighbor is added, tx counters are set to
zero and then based on this, it is further decided to send hello in
pim_hello_require function.
Fix:
====
Separating the hello statistics and the logic to decide when to send hello
based on a new flag. pim_ifstat_hello_sent will be used to note down
the hello stats while a new flag is added to decide whether to send hello
or not if it is the first packet to a neighbor.
