This isn't a system or interface setting, it's a socket behavior. It is
both irrelevant and confusing to the user since it doesn't affect any
system behavior (but it sounds like it does). Whether it is enabled or
not is solely relevant to how the code is designed to work.
So, remove it from output.

Since `zvni_map_to_svi_ns()` is used to find and return one specific interface
based on passed attributes of SVI, so the two parameters `in_param` and `p_ifp`
must not be NULL.
Passing NULL `p_ifp` makes no sense, so the check `if (p_ifp)` is
unnecessary.
So use `assert` to ensure the two parameters, and remove that unnecessary check.

The prefix_master->str data structure was a sorted
list of the prefix names. Not that big of a deal
other than insertion and deletion is insanely expensive
when you have a large number of unique prefix-lists.
In my test config file that I discovered this,
I have 587 unique prefix lists spread out acros
~26k lines of prefix-lists. When reading
this config file into FRR the read time goes
from 690 seconds to 650 seconds.

Fixing the below problem:
Dereferencing a pointer that might be "NULL" "group_dnode"
when calling "yang_is_last_list_dnode" in api pim_process_no_rp_cmd
Although there is no NULL pointer dereference since
yang_dnode_exists is called before using the dnode.
So removing the unnecessary yang_dnode_exists api call
and directly get the node and if node does not exists,
return.

Keep the list of remote-vteps/nexthops in
rmac db.
Problem:
In CLAG deployment there might be a situation
where CLAG secondary sends individual ip as nexthop
along with anycast mac as RMAC. This combination
is updated in zebra's rmac cache.
Upon recovery at clag secondary sends withdrawal
of the incorrect rmac and nexthop mapping.
The RMAC entry mapping to nh is not cleaned up properly
in the zebra rmac cache.
Fix:
Zebra rmac db needs to maintain a list of nexthops.
When a bgp withdrawal for rmac to nexthop mapping
is received, remove the old nexthop from the rmac's nh
list and if the host reference still remains for
the RMAC,fall back to the nexthop one remaining in
the list.
At most you expect two nexthops mapped to RMAC
(in clag deployment).
Ticket: 2798406

Testing Done:
CLAG primary and secondary have advertise-pip enabled
advertise type-5 route (default route) with
individual IP as nh and individual svi mac as rmac.
- disable advertise pip on both clag devices, this
results in advertisement of routes with anycast ip as nh
and anycast mac as rmac.
- disable peerlink on clag primary, this triggers
clag secondary to (transitory) send bgp update with
individual ip as nh and anycast mac as rmac.
- At the remote vtep:
Check the zebra's rmac cache/nh mapping correctly
and points to anycast rmac and anycast ip as nh of the
clag system.

When we are processing a bond member's protodown we get from
the dataplane, check to make sure we haven't already queued
up a set. If we have, it's likely this is just a notification
we get from the kernel after we set protodown and before we have
processed the result in our dplane pthread.
This change is needed now that we set protodown via the dplane
pthread.

Only clear protodown reason on shutdown/sweep, retain protodown

This is to retain traditional and expected behavior with daemons

and retained on bring up to prevent traffic from being dropped.
We must cleanup our reason code though to prevent us from blocking
others.
