to support IPv6 as well as IPv4 (a work in progress).
Make the second argument of af_status() a bool instead of an int.
Exit early with an error if the operator specifies an unsupported
address family on the command line. The change should help rc
scripts to detect that IPv6 support is missing from the kernel,
with 'ifconfig lo0 inet6'.
Start using prop_dictionary_util(3).
improved modularity and extensibility.
In the new architecture, a directed graph of argument-matching
objects (match objects) expresses the set of feasible ifconfig
statements. Match objects are labelled by subroutines that provide
the statement semantics.
Many IPv4, IPv6, 802.11, tunnel, and media configurations have been
tested.
AppleTalk, ISO, carp(4), agr(4), and vlan(4) configuration need
testing.

While here, use estrlcpy instead of strncpy.
From FreeBSD ifconfig and net80211
to modify the whole VLAN tags, but it is permitted to change 12-bit
VLAN identificators only. Reflect this fact on the appropriate man
pages.
Antti Kantee and Mihai Chelaru from #netbsd-code were helpful in
better understanding of VLAN stuff. Thank you!
Also, add ioctls SIOCGIFADDRPREF/SIOCSIFADDRPREF to get/set preference
numbers for addresses. Make ifconfig(8) set/display preference
numbers.
To activate source-address selection policies in your kernel, add
'options IPSELSRC' to your kernel configuration.
Miscellaneous changes in support of source-address selection:
1 Factor out some common code, producing rt_replace_ifa().
2 Abbreviate a for-loop with TAILQ_FOREACH().
3 Add the predicates on IPv4 addresses IN_LINKLOCAL() and
IN_PRIVATE(), that are true for link-local unicast
(169.254/16) and RFC1918 private addresses, respectively.
Add the predicate IN_ANY_LOCAL() that is true for link-local
unicast and multicast.
4 Add IPv4-specific interface attach/detach routines,
in_domifattach and in_domifdetach, which build #ifdef
IPSELSRC.
See in_getifa(9) for a more thorough description of source-address
selection policy.
Fix MOBILE encapsulation. Add many debugging printfs (mainly
concerning UDP mode). Clean up the gre(4) code a bit. Add the
capability to setup UDP tunnels to ifconfig. Update documentation.
In UDP mode, gre(4) puts a GRE header onto transmitted packets,
and hands them to a UDP socket for transmission. That is, the
encapsulation looks like this: IP+UDP+GRE+encapsulated packet.
There are two ways to set up a UDP tunnel. One way is to tell the
source and destination IP+port to gre(4), and let gre(4) create
the socket. The other way to create a UDP tunnel is for userland
to "delegate" a UDP socket to the kernel.
if the kernel does not set the interface up after we set an address,
do it explicitly, unless we (previously) set it down on user request.
This will allow the network drivers to be "fixed" while keeping visible
behaviour the same. Part of fixing PR 30694.
ifconfig(8) from printing errors like "ifconfig: socket: Address
family not supported by protocol family" when examining the status
of a network interface.
