b59dcaeeb3 - Use size_t instead of int when appropriate;
- Use C99 sparse initialization.

With these changes ifconfig(8) is WARNS=2 clean.

9c1fd0b05f Replace clone_setcallback() with a new function clone_setdefcallback()
that selects a callback from an interface prefix name. This allows us to
report a meaningful error when the user types 'ifconfig wlan0 create',
for example, and also kills some redundant code.

2fa02c5fb7 Fix handling of create operation together with setting other parameters:
o mark cmds/parameters to indicate they are potential arguments to a clone
  operation (e.g. vlantag)
o when handling a create/clone operation do the callback on seeing the first
  non-clone cmd line argument so the new device is created and can be used;
  and re-setup operating state to reflect the newly created device

0cae11b9cc Remove IPX over IP tunneling pieces from ifconfig(8), omitted portion of
previous commit:

  Remove IPX over IP tunneling support, which allows IPX routing over IP
  tunnels, and was not MPSAFE.  The code can be easily restored in the
  event that someone with an IPX over IP tunnel configuration can work
  with me to test patches.

  This removes one of five remaining consumers of NET_NEEDS_GIANT.

8f3591a5bb Update for revised 802.11 support:
o revised channel handling support; ifconfig now queries the kernel to
  find the list of available channels and handles channel promotion;
  channel attributes can be specified as part of the channel; e.g. 36:a
  for channel 36 in 11a (as opposed to turbo A or HT A)
o use channel list to map between freq and IEEE channel #; this eliminates
  all knowledge of how the mapping is done and fixes handling of cases
  where channels overlap in the IEEE channel # space but are distinct in
  the frequency+attributes space (e.g. PSB)
o add new knobs: bgscan, ff (Atheors fast frames), dturbo (Atheros
  Dynamic Turbo mode), bgscanidle, bgscanintvl, scanvalid, roam:rssi11a,
  roam:rssi11b, roam:rssi11g, roam:rate11a, roam:rate11b, roam:rate11g
  (roaming parameters), burst, doth (forthcoming 11h support)
o print contents of WME, ATH, WPA, RSN, information elements with -v option
o print signal strength in dBm
o print noise floor in dBm
o add list txpow to print tx power caps/channel
o change default channel display in status to be more informative

b7eb47e290 Add a new flag '-k' to ifconfig(8), indicating that it is alright to
print potentially sensitive keying material to stdout.  With the new
802.11 support, ifconfig(8) is now capable of printing 802.11 keys,
and did by default for the root user, which is undesirable in some
environments.  Now it will not print keying material unless requested
(and available to the user).

90c4b74cbe Fix special status reporting. Prior to the reorg there was
special-purpose code to display status for an interface for
state that was not address-oriented.  This status reporting
was merged in to the address-oriented status reporting but
did not work for link address reporting (as discovered with
fwip interfaces).  Correct this mis-merge and eliminate the
bogus kludge that was used for link-level address reporting.

o add an af_other_status method for an address family for
  reporting status of things like media, vlan, etc.
o call the af_other_status methods after reporting address
  status for an interface
o special-case link address status; when reporting all
  status for an interface invoke it specially prior to
  reporting af_other_status methods (since it requires the
  sockaddr_dl that is passed in to status separately from
  the rtmsg address state)
o correct the calling convention for link address status;
  don't cast types, construct the proper parameter

This fixes ifconfig on fwip interfaces.

5faf8dcb55 Overhaul to cleanup some of the tangled logic that's grown over the years.
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

a4fa9864bf Use IFNAMSIZ instead of a magic value for the length of an interface
name.

Prevent the kernel from potentially overflowing the interface name
variable.  The size argument of strlcpy is complex because the name is
not null-terminated in sdl_data.

regarding 802.1 MAC and Mandatory Access Control (MAC).  Some
potential for confusion remains further in other areas of the
system regarding Message Authentication Codes (MAC).

ca299b1fc0 When using interfaces that support if_media, the supported media list is
printed on a single, very long, and generally unreadable line.  This
isn't very useful.  It's also really ugly and most of the time you don't
care what media is supported anyway.

419d8080a4 Currently, each wireless networking driver has it's own control program
despite the fact that most people want to set exactly the same settings
regardless of which card they have.  It has been repeatidly suggested
that this configuration should be done via ifconfig.  This patch
implements the required functionality in ifconfig and add support to the
wi and an drivers.  It also provides partial, untested support for the
awi driver.
