Enable to remove multiple ARP/NDP entries for one destination
The kernel can have multiple ARP/NDP entries which have an indentical
destination on different interfaces. This is normal and can be
reproduce easily by ping -I or ping6 -S. We should be able to remove
such entries.
arp -d <ip> and ndp -d <ip> are changed to fetch all ARP/NDP entries
and remove matched entries. So we can remove multiple entries
described above. This fetch all and selective removal behavior is
the same as arp <ip> and ndp <ip>; they also do fetch all entries
and show only matched entries.

ozaki-r | Fix usage of routing messages on arp -d and ndp -d
It didn't work as we expected; we should set RTA_GATEWAY not
RTA_IFP on RTM_GET to return an if_index and the kernel should
use it on RTM_DELETE.

Separate nexthop caches from the routing table
By this change, nexthop caches (IP-MAC address pair) are not stored
in the routing table anymore. Instead nexthop caches are stored in
each network interface; we already have lltable/llentry data structure
for this purpose. This change also obsoletes the concept of cloning/cloned
routes. Cloned routes no longer exist while cloning routes still exist
with renamed to connected routes.
Noticeable changes are:
- Nexthop caches aren't listed in route show/netstat -r
- sysctl(NET_RT_DUMP) doesn't return them
- If RTF_LLDATA is specified, it returns nexthop caches
- Several definitions of routing flags and messages are removed
- RTF_CLONING, RTF_XRESOLVE, RTF_LLINFO, RTF_CLONED and RTM_RESOLVE
- RTF_CONNECTED is added
- It has the same value of RTF_CLONING for backward compatibility
- route's -xresolve, -[no]cloned and -llinfo options are removed
- -[no]cloning remains because it seems there are users
- -[no]connected is introduced and recommended
to be used instead of -[no]cloning
- route show/netstat -r drops some flags
- 'L' and 'c' are not seen anymore
- 'C' now indicates a connected route
- Gateway value of a route of an interface address is now not
a L2 address but "link#N" like a connected (cloning) route
- Proxy ARP: "arp -s ... pub" doesn't create a route
You can know details of behavior changes by seeing diffs under tests/.

It didn't work as we expected; we should set RTA_GATEWAY not
RTA_IFP on RTM_GET to return an if_index and the kernel should
use it on RTM_DELETE.
Improve backward compatibility of (fake) routing messages on adding an ARP/NDP entry
A message originally included only DST and GATEWAY. Restore it.
Fix ifdef; care about a case w/ INET6 and w/o INET
Drop RTF_UP from a routing message of a deleted ARP/NDP entry
Check existence of ARP/NDP entries
Checking ARP/NDP entries is valid rather than checking routes.
Fix wrong comment
Drop RTF_LLINFO flag (now it's RTF_LLDATA) from local routes
They don't have llinfo anymore. And also the change fixes unexpected
behavior of ARP proxy.
Restore ARP/NDP entries to route show and netstat -r
Requested by dyoung@ some time ago
Enable to remove multiple ARP/NDP entries for one destination
The kernel can have multiple ARP/NDP entries which have an indentical
destination on different interfaces. This is normal and can be
reproduce easily by ping -I or ping6 -S. We should be able to remove
such entries.
arp -d <ip> and ndp -d <ip> are changed to fetch all ARP/NDP entries
and remove matched entries. So we can remove multiple entries
described above. This fetch all and selective removal behavior is
the same as arp <ip> and ndp <ip>; they also do fetch all entries
and show only matched entries.
