the case our default conflicts with another application
they are using.

Add support for setting protodown via sharpd. This is just useful
for testing. We can make use of this in topotests.

Add support for setting the protodown reason code.
829eb208e8
These patches handle all our netlink code for setting the reason.
For protodown reason we only set `frr` as the reason externally
but internally we have more descriptive reasoning available via
`show interface IFNAME`. The kernel only provides a bitwidth of 32
that all userspace programs have to share so this makes the most sense.
Since this is new functionality, it needs to be added to the dplane
pthread instead. So these patches, also move the protodown setting we
were doing before into the dplane pthread. For this, we abstract it a
bit more to make it a general interface LINK update dplane API. This
API can be expanded to support gernal link creation/updating when/if
someone ever adds that code.
We also move a more common entrypoint for evpn-mh and from zapi clients
like vrrpd. They both call common code now to set our internal flags
for protodown and protodown reason.
Also add debugging code for dumping netlink packets with
protodown/protodown_reason.

Contraints of host routes are too strict in current code:
Host routes with same destination address and nexthop address are forbidden
even when cross VRFs.
Currently host routes with different destination and nexthop address can cross
VRFs, it is ok. But host routes with same addresses are forbidden to cross VRFs,
it is wrong.
Since different VRFs can have the same addresses, leak specific host route with
the same nexthop address ( it means destination address is same to nexthop
address ) to other VRFs is a normal case.
This commit relaxes that contraints. Host routes with same destination address
and nexthop address are forbidden only when not cross VRFs.

When an interface goes down, it signals any related NHGs to
re-validate themselves. During zebra shutdown, ensure we remove
any NHGs we've installed.

Added this api to fill all multicast group address based on IP version.
For PIMv4 its 224.0.0.0/4, for PIMv6 its FF00::0/8.
Changed the code where its being used currently.

Pass pim_addr as parameter for rp address to accomodate ipv6.
Modifying pim_rp_cmd_worker and pim_no_rp_cmd_worker function
parameters from in_addr to pim_addr.
Changes in the caller functions are done as well to make it work
for IPv6.

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.

1. Moving the processing of the above command to an api.
2. Change DEFUN to DEPFY
3. Make the api common for pimv4 and pimv6 processing.

Modify the apis pim_process_rp_cmd and pim_process_no_rp_cmd
to accomodate ipv4 as well as ipv6.

The pattern defined for ipv6-multicast-group-prefix is wrong.
This is leading to mismatch for all the valid ipv6 multicast
addresses.

Commit: ea47320b1d
Modified the bgp_clear_stale_route function to have
better indentation, but in the process changed some
`continue;` statements to `break;` which modified
the looping and caused stale paths to not always be
removed upon an update.
To reproduce: A ---- B, setup with addpath and GR
One side has a prefix with nhop1 and nhop2, kill one
side and then resend the same prefix with nhop3,
paths nhop1 and 2 become stale and never removed.
Code inspection clearly shows that that `continue`
statements became `break` statements causing the
loop over all paths to stop prematurely.
The fix is to change the break back to continue
statements so the loop can continue instead of
stopping.

- rather than coerce `const char *` to std:string&, just pass the
C ptr, as that's what is used anyway.
