1. Explicitly dump IP addresses.
Currently, some IP addresses are dumped using netcfg, but that
only dumps the first IPv4 address on each interface. Instead,
call ip -4 addr and ip -6 addr explicitly to dump all IPv4 and
IPv6 addresses on the system.
2. Disable dumping /proc/net/{ipv6,}route, because:
- We already dump all IPv4 and IPv6 routes in the tables that
we use.
- /proc/net/route is confusing because it only includes routes
in the main table, which are all but unused. It's also in
unreadable host-byte-order hex.
- /proc/net/ipv6_route is confusing because it includes routes
from all tables but does not say what table they are in.
3. Instead of dumping the contents of /proc/net/arp , use
"ip -4 neigh show" and "ip -6 neigh show" to dump the
neighbour caches for both IPv4 and IPv6.
