Overhaul to cleanup some of the tangled logic that's grown over the years.

Browse Source 
o break per-address family support out into separate files
o modularize per-address family and functional operations using
  a registration mechanism; this permits configuration according
  to which files you include (but beware that order of the files
  is important to insure backwards compatibility)
o many cleanups to eliminate incestuous behaviour, global variables,
  and poor coding practices (still much more to fix)

The original motivation of this work was to support dynamic addition
of functionality based on the interface so we can eliminate the various
little control programs and so that vendors can distribute ifconfig
plugins that support their in-kernel code.  That work is still to be
completed.

o Update 802.11 support for all the new net80211 functionality; some
  of these operations (e.g. list *) may be better suited in a different
  program

If the interface was reset when previously marked down,

.It Cm ssid Ar ssid
For IEEE 802.11 wireless interfaces, set the desired Service Set
Identifier (aka network name).
The SSID is a string up to 32 characters
in length and may be specified as either a normal string or in
hexadecimal when proceeded by
.Ql 0x .
Additionally, the SSID may be cleared by setting it to
.Ql - .
.It Cm nwid Ar ssid
Another name for the
.Cm ssid
parameter.
Included for

compatibility.
.It Cm stationname Ar name
For IEEE 802.11 wireless interfaces, set the name of this station.
It appears that the station name is not really part of the IEEE 802.11
protocol though all interfaces seem to support it.
As such it only
seems to be meaningful to identical or virtually identical equipment.
Setting the station name is identical in syntax to setting the SSID.
.It Cm station Ar name
Another name for the
.Cm stationname
parameter.
Included for
.Bsx
compatibility.
.It Cm channel Ar number
For IEEE 802.11 wireless interfaces, set the desired channel.
Channels range from 1 to 14, but the exact selection available
depends on the region your adaptor was manufactured for.
Setting
the channel to 0 will give you the default for your adaptor.
Many
adaptors ignore this setting unless you are in ad-hoc mode.

wireless clients directly (default).
To instead let them pass up through the
system and be forwarded using some other mechanism use
.Dq Li -apbridge.
Disabling the internal bridging
is useful when traffic is to be processed with
packet filtering.
.It Cm authmode Ar mode
For IEEE 802.11 wireless interfaces, set the desired authentication mode
in infrastructure mode.
Set the desired authentication mode in infrastructure mode.
Not all adaptors support all modes.
The set of
valid modes is
.Dq Li none ,
.Dq Li open ,
.Dq Li shared (shared key),
.Dq Li 8021x (IEEE 802.1x),
or
.Dq Li wpa (IEEE WPA/WPA2/802.11i).
The
.Dq Li 8021x
and
.Dq Li shared .
.Dq Li wpa
modes are only useful when used an authentication service
(a supplicant for client operation or an authenticator when
operating as an access point).
Modes are case insensitive.
.It Cm bssid Ar address
Specify the MAC address of the access point to use when operating
as a station in a BSS network.
This overrides any automatic selection done by the system.
To disable a previously selected access point supply
.Dq Li any ,
.Dq Li none ,
or
.Dq Li -
for the address.
This option is useful when more than one access points have the same SSID.
Another name for the
.Cm bssid
parameter is
.Cm ap .
.It Cm chanlist Ar channels
Set the desired channels to use when scanning for access
points, neighbors in an IBSS network, or looking for unoccupied
channels when operating as an access point.
The set of channels is specified as a comma-separated list with
each element in the list either a single channel number of a range
of the form
.Dq Li a-b .
Channel numbers must be in the range 1 to 255 and be permissible
according to the operating characteristics of the device.
.It Cm channel Ar number
Set a single desired channel.
Channels range from 1 to 255, but the exact selection available
depends on the region your adaptor was manufactured for.
Setting
the channel to
.Dq Li 0 ,
.Dq Li any ,
or
.Dq Li -
will give you the default for your adaptor.
Many
adaptors ignore this setting unless you are in ad-hoc mode.
Alternatively the frequency, in megahertz, may be specified
instead of the channel number.
.It Cm hidessid
When operating as an access point do not broadcast the SSID
in beacon frames.
By default the SSID is included in beacon frames.
To re-enable the broadcast of the SSID use
.Fl hidessid .
.It Cm powersave
For IEEE 802.11 wireless interfaces, enable powersave mode.
.It Fl powersave
For IEEE 802.11 wireless interfaces, disable powersave mode.
Enable powersave operation.
When operating as a client the station will conserve power by
periodically turning off the radio and listening for
messages from the access point telling it there are packets waiting.
The station must then retrieve the packets.
When operating as an access point the station must honor power
save operation of associated clients.
Not all devices support power save operation, either as a client
or as an access point.
Use
.Fl powersave
to disable powersave operation.
.It Cm powersavesleep Ar sleep
For IEEE 802.11 wireless interfaces, set the desired max powersave sleep
time in milliseconds.
Set the desired max powersave sleep time in milliseconds.
.It Cm protmode Ar technique

is broken.

.Dq Li device

.Dq Li auto

.Dq Li manual

By the default the device is left to handle this if it is
capable; otherwise the operating system will automatically
attempt to reestablish communication.
Manual mode is mostly useful when an application wants to
control the selection of an access point.

Set the desired Service Set Identifier (aka network name).
The SSID is a string up to 32 characters
in length and may be specified as either a normal string or in
hexadecimal when proceeded by
.Ql 0x .
Additionally, the SSID may be cleared by setting it to
.Ql - .
.It Cm scan
Display the current set of scanned neighbors and/or trigger a new scan.
Only the super-user can trigger a scan.
.It Cm stationname Ar name
Set the name of this station.
It appears that the station name is not really part of the IEEE 802.11
