Revert to previous as the atf tests are still failing.

Use existing address when setting parameters.

No need to specify address every time when setting broadcast address or
netmask.

Hopefully successfully re addresses PR bin/10911.

Revert to previous as atf tests were failing.

No need address every time to specify broadcast and netmask.

Previously ifconfig would fail silently.

Addresses PR bin/10911.

Update for proplib(3) API changes.

Mostly merge changes from HEAD upto 20200411

PR/46579: Takahiro HAYASHI: ifconfig clone destroy should not print useless
diagnostic and exit with an error code. Get the interface name and flags
opportunistically to allow the code to return normally if it does not need

Let us add/remove features from ifconfig, such as support for
various address families (inet, inet6, iso, atalk) and protocols
(802.11, 802.3ad, CARP), simply by trimming the list of sources in
the Makefile.  This helps one customize ifconfig for an embedded
device or for install media, and it eliminates a lot of grotty
#ifdef'age.  Now, the ifconfig syntax and semantics are finalized
at run-time using the constructor routines in each address-family/protocol
module.

(In principle, ifconfig could load virtually all of its syntax from
shared objects.)

Extract a lot of common code into subroutines, in order to shrink
the ifconfig binary a bit.  Make all of the address families share
code for address addition/replacement/removal, and delete "legacy"
code for manipulating addresses.  That may have broken atalk and
iso, despite my best efforts.

Extract an include file, Makefile.inc, containing the make-fu that
both ifconfig and x_ifconfig share.

Sprinkle static.  Change some int's to bool's.  Constify.

Add RCS Ids to carp.c and env.c.  Move media code to a new file,
media.c.  Delete several unneeded header files.

Set, reset, and display the IEEE 802.11 attribute, 'dot11RTSThreshold'.

Bug fix: do not require both a interface address and a destination
address for point-to-point interfaces, but accept a interface
address by itself.

*Always* pass the prefix mask specified on the command line, even
on an IFF_POINTOPOINT interface.  Patch tested by John Klos and
found to fix the bug he reported on tech-net@, "Subject: Can't use
gif in -current".

Cosmetic: add missing /*FALLTHROUGH*/.

Apply netmasks to !(IFF_BROADCAST|IFF_POINTOPOINT) interfaces as
well as to IFF_BROADCAST interfaces.  Fixes the bug reported by
Markus W Kilbinger,

	ifconfig stf0 inet6 2002:xxxx:76ec:0001::1 prefixlen 16 alias

results in the wrong configuration,

	stf0: flags=1<UP> mtu 1280
		inet6 2002:xxxx:76ec:1::1 prefixlen 64

Apply the right copyright notice.

Let the address family modules zero initialize their own ifreqs,
instead of zeroing them in commit_address().

Switch to in6_commit_address() from in6_getprefix() and in6_getaddr().

Temporarily add some debugging code to setia6eui64_impl().

Move IPv4/IPv6-specific code from commit_address() to in_commit_address()
and in6_commit_address().  Fixes the USE_INET6=no build.

Use prop_dictionary_util(3).

Use prop_dictionary_util(3) some more.

When we read interface flags and capabilities from the kernel, take
care not to record them in our current environment (env), but record
them in the output environment (oenv), instead.  This helps us get
interface capabilities and flags right.

Rename in_addr_commit() to commit_address(), and refactor slightly
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).

Overhaul ifconfig.  Use fewer global variables.  Take a leap toward
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.
