4fdd2942c5 pimd: Warn when we try to build MAXVIFS > 256 
We use the pim mroute socket for kernel notifications of events.
Currently this is limited to 8 bits of data.  There are patches
coming down the pike in kernel land to allow this to expand.
Rather than fix this and all the other places we assume MAXVIFS < 256
in the pim code right now.  Leave a land mine for the developer
doing this work to point them in the right direction.

1b741a01c6 nhrpd: add frr-vrf to the list of implemented yang modules 
PR #6376 introduced a VRF leafref in the frr-interface YANG module.
That change exposed a bug in the northbound layer that is causing
nhrpd to crash under certain circumstances. Even though nhrpd wasn't
converted to the new northbound model yet, make it implement the
frr-vrf module in order to work around this problem. This is a
temporary fix until a better solution is available.

we need to check for that.

Interestingly it appears we don't crash even when this is the case.

8336c896fd bgpd: Add neighbor <neigh> shutdown rtt command 
This would be useful in cases with lots of peers and shutdown them
automatically if RTT goes above the specified limit.

A host with 512 or more IPv6 addresses has a higher latency due to
ipv6_addr_label(). This method tries to pick the best candidate address
fo outgoing connection and literally increases processing latency.
