1. This check is absolutely useless. Nothing keeps user from deleting
the address right after this check.
2. This check prevents zebra from correctly reading the user config with
"set src" because of a race with interface startup (see #4249).
3. NO OPERATIONAL DATA USAGE ON VALIDATION STAGE.
Fixes#7319.

The only difference in daemons' interface node definition is the config
write function. No need to define the node in every daemon, just pass
the callback as an argument to a library function and define the node
there.

There exists some rare situations where fpm will attempt
to send a route update with no valid nexthops. In that
case an assert would be hit. This is not good for
trying to keep your routing daemons up and running
when we can safely just recover the situation.
Fixes#7588

Currently 'show evpn rmac vni .. mac .. json' includes fields for
localSequence and remoteSequence, which are misleading since they
aren't applicable to a macs in the IP-VRF mac table (RMAC).
This removes the localSequence + remoteSequence fields from the output.

like the other automake variables, setting `xyz_LDFLAGS` causes
`AM_LDFLAGS` to be ignored for `xyz`. For some reason I had in my mind
that automake doesn't do this for LDFLAGS, but... it does. (Which is
consistent with `_CFLAGS` and co.)
So, all the libraries and modules have been ignoring `AM_LDFLAGS` (which
includes `SAN_FLAGS` too). Set up new `LIB_LDFLAGS` and
`MODULE_LDFLAGS` to handle all of this correctly (and move these bits to
a central location.)
Fixes: #9034

When port was removed from last access vlan, the linux kernel
won't send any vlan info in the netlink message, it might affact

Current code was allowing redistribution of kernel routes from
the non-default non vrf tables once FRR was already up and running.
In the case where we add `redistribute kernel` in an upper level
protocol we never consider the non-default vrf or non-vrf tables
so it is never accepted.
In the case where a kernel route is added after `redistribute kernel`
is already in place we were never looking at the fact that the
route was in a non-default non-vrf table. This code fixes
that issue.

At some point we broke the ifp pointer for nhe->ifp such
that it was pointing to an interface even in groups/recurisve
instances.
Add checks here to make it again so that we only set the ifp
pointer if it is a fully resolved singleton NHE.

In the reachability code we auto pass back the fully resolved
nexthops. Modify the ZEBRA_IPV4_NEXTHOP_LOOKUP_MRIB code
to do the exact same thing so that the zclient_lookup_nexthop
code does not need to recursively look for the data that
zebra already has.

Basically, this is handled by JSON-C library. I've compiled with the
latest release of json-c and it works well.
Didn't test with various distribution versions, but this change is kinda
dependend from the json-c lib version the distra has.
Before:
```
"192.168.100.1\/32":[
{
"prefix":"192.168.100.1\/32",
```
After:
```
"192.168.100.1/32":[
{
"prefix":"192.168.100.1/32",

There are a few places in the code where we use PREFIX_COPY(_IPV4/IPV6)
macro to copy a prefix. Let's always use prefix_copy function for this.
This should fix CID 1482142 and 1504610.

Include the complete set of primary and backup nexthops from
the resolving route for a pseudowire. Add accessors for that
info. Modify the logic that creates the fib set of pw nexthops
so that only installed, labelled nexthops are included.

Modify the pseudowire reachability logic so that it returns
success if there is at least one installed labelled nexthop for
the route resolving the pw destination. We also check for
valid backup nexthops if necessary, in case there's been a
switchover event.
Only OpenBSD requires that _all_ nexthops be labelled, so we
have a more strict version of the logic also.
