 We can assume that rt_ifp is always non-NULL.
 Sending a routing message (RTM_ADD) on adding an llentry
 A message used to be sent on adding a cloned route. Restore the
 behavior for backward compatibility.
 Requested by ryo@
 Drop RTF_CONNECTED from a result of RTM_GET for ARP/NDP entries
 ARP/NDP entries aren't connected routes.
 Reported by ryo@
 Support -c <count> option for route monitor
 route command exits if it receives <count> routing messages where
 <count> is a value specified by -c.
 The option is useful to get only particular message(s) in a test script.
 Test routing messages emitted on operations of ARP/NDP entries
 Do netstat -a for an appropriate protocol
 Add missing declarations for cleanup
 Set net.inet.arp.keep only if it's required
 Don't create a permanent L2 cache entry on adding an address to an interface
 It was created to copy FreeBSD, however actually the cache isn't
 necessary. Remove it to simplify the code and reduce the cost to
 maintain it (e.g., keep a consistency with a corresponding local
 Fix typo
 Fix in_lltable_match_prefix
 The function has not been used but will be used soon.
 Remove unused function (nd6_rem_ifa_lle)
 Allow in6_lltable_free_entry to be called without holding the afdata lock of ifp as well as in_lltable_free_entry
 This behavior is a bit odd and should be fixed in the future...
 Purge ARP/NDP entries on an interface when the interface is down
 Fix PR kern/51179
 Purge all related L2 caches on removing a route
 The change addresses situations similar to PR 51179.
 Purge L2 caches on changing an interface of a route
 The change addresses situations similar to PR 51179.
 Test implicit removals of ARP/NDP entries
 One test case reproudces PR 51179.
 Fix build of kernels without both INET and INET6
 Tweak lltable_sysctl_dumparp
 - Rename lltable_sysctl_dumparp to lltable_sysctl_dump
   because it's not only for ARP
 - Enable it not only for INET but also for INET6
 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.
 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.
 Related to PR 51179
 Check if ARP/NDP entries are purged when a related route is deleted
