usr.sbin/ldpd : adjacency.c hello.c packet.c
Log message:
Rework the handling of Hello packets.
With the introduction of IPv6 support by RFC 7552, the handling of Hello
packets in ldpd became something incredibly complex. Neighbors can change
from single-stack LDP to dual-stack and vice-versa. They can change
their transport preference, their transport addresses (IPv4 and IPv6)
and even start or stop sending the Dual-Stack TLV. We also have to take
care to reject things like multiple adjacencies advertising different
transport-addresses for the same neighbor. ldpd was failing for some of
the cases mentioned above, this patch fixes these issues and attempts
to make the code easier to read.
