- ip-neighbour: generic neighbour handling; APIs, DBs, event handling,
aging
- arp: ARP protocol implementation
- ip6-nd; IPv6 neighbor discovery implementation; separate ND,
MLD, RA
- ip6-link; manage link-local addresses
- l2-arp-term; events separated from IP neighbours, since they are not
the same.
vnet retains just enough education to perform ND/ARP packet
construction.
arp and ip6-nd to be moved to plugins soon.

To avoid excessive bursts, pacer must be provided with an estimated rtt
for the connection. That's used to compute an idle timeout, i.e., time
after which the bucket is reset to 1 mtu due to inactivity. For now,
idle timeout is computed as 5% of the rtt.

Add infra that allows transpors to enqueue pending buffers without the
need to build and manage their own pending frames. An important benefit
is the fact that buffer wire/tx ordering is ensured by session layer.
