Subject: [PATCH] zebra: fix missing route-advert stubs
Stubs are used when frr is built without route-advert
support; a couple of apis were missing, causing builds to fail.

Subject: [PATCH 1/3] bgpd: Update failed reason to distinguish some NHT
scenarios
Current failed reasons for bgp when you have a peer that
is not online yet is `Waiting for NHT`, even if NHT has
succeeded. Add some code to differentiate this.
eva# show bgp ipv4 uni summ failed
BGP router identifier 192.168.201.135, local AS number 3923 vrf-id 0
BGP table version 0
RIB entries 0, using 0 bytes of memory
Peers 2, using 43 KiB of memory
Neighbor EstdCnt DropCnt ResetTime Reason
192.168.44.1 0 0 never Waiting for NHT
192.168.201.139 0 0 never Waiting for Open to Succeed
Total number of neighbors 2
eva#
eva# show bgp nexthop
Current BGP nexthop cache:
192.168.44.1 invalid, peer 192.168.44.1
Must be Connected
Last update: Mon Feb 10 19:05:19 2020
192.168.201.139 valid [IGP metric 0], #paths 0, peer 192.168.201.139
So 192.168.201.139 is a peer for a connected route that has not been
created on .139, while 44.1 nexthop tracking has not succeeded yet.

Subject: [PATCH 2/3] bgpd: Show the real reason why the peer is failed
If the peer was shutdown locally, it doesn't show up as admin. shutdown.
Instead it's treated as "Waiting for peer OPEN".
The same applies to when the peer reaches maximum-prefix count.

Add a config that disables use of kernel-level nexthop ids.
Currently, zebra always uses nexthop ids if the kernel supports
them.

Subject: [PATCH 2/2] zebra: determine src when using nexthop objects
Determine src based on nexthop data even when we are using
kernel nexthop objects.
Before, we were entirely skipping this step and just sending the
nexthop ID, ignoring src determination.

Subject: [PATCH] zebra: free unhashable (dup) NHEs via ID table cleanup
Free unhashable (duplicate NHEs from the kernel) via ID table
cleanup. Since the NHE ID hash table contains extra entries,
that's the one we need to be calling zebra_nhg_hash_free()
on, otherwise we will never free the unhashable NHEs.
This was found via a memleak:

(for context, the defaults code originally didn't have a dedicated

adding bool as a separate case :( )
