These will corrupt memory if mroute_vif_index is -1 (e.g. interface not
operating.) That shouldn't happen, but it does while doing development
work, so trip an assert rather than corrupting memory.

Currently the nexthop tracking code is only sending to the requestor
what it was requested to match against. When the nexthop tracking
code was simplified to not need an import check and a nexthop check
in b8210849b8 for bgpd. It was not
noticed that a longer prefix could match but it would be seen
as a match because FRR was not sending up both the resolved
route prefix and the route FRR was asked to match against.
This code change causes the nexthop tracking code to pass
back up the matched requested route (so that the calling
protocol can figure out which one it is being told about )
as well as the actual prefix that was matched to.

sockopt_cork is a no-op function that was cleaned up
in 2017. Since then it's still not being used. At
this point in time there is little point in keeping a
dead function that will not be used because of vagaries
between platforms
Signed-off-by: Donald Sharp <sharpd@nvidia.com>
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.

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.

1. Return value of this function pim_rp_del_config is nowhere used.
So made it as a void function.
2. Paramater const char *rp is first converted to string from prefix
in the caller and then back to prefix in this api pim_rp_del_config.
Fixed it by directly passing the address instead of string.

Problem Statement:
=================
PIM Logs are coming at interval of 1 minute although pim
is not enabled.
Root Cause Analysis:
====================
By default, RCPM configures the PIM debugs when router comes up
via script. The product cannot disable PIM even though it is not required.
Hence moving these logs under a new debug option which will not be
enabled by default.
Fix:
====
Added a new option "detail" in the cli:
debug pim nht detail

Currently the code is expecting the TOS value for received
packet to be 0xC0 and hence it is discarding packets having
TOS value other than 0xc0.
We need to make sure that we are sending the packet with
TOS 0xC0 and while receiving we can allow any TOS value.
Let's follow Postel's law.

The pim_upstream data structure has a ref count that is
not properly being incremented/decremented and when an
instance is removed this is causing crashes because timers
are still popping afterwords on data structures that are
now freed.
Since getting the ref count code is extremely hard and
we know that this crash is happening, add a bit of code
to prevent the timers from popping at all when we go
through and free up other data structures that we
are pointing at.

This creates `pim6_stubs.c`, which is intended to temporarily provide
stubbed-out definitions of some functions we don't have yet for IPv6.
This makes pim6d compile without the `PIM_V6_TEMP_BREAK` hack, and is

further work.
