6fe2e1762e ifconfig(8): can't use 'name' or 'description' when creating interface with auto numbering
If one does 'ifconfig tap create name blah', it will return error because the
'name' command doesn't properly populate the request sent to ioctl(...). The
'description' command has the same bug, and is also fixed with this patch.

If one does 'ifconfig tap create mtu 9000 name blah', it DOES work, but 'tap0'
(or other sequence number) is echoed, instead of the expected 'blah'. (assuming
the name change actually succeeded)

08b68b0e4c A major overhaul of the CARP implementation. The ip_carp.c was started
from scratch, copying needed functionality from the old implemenation
on demand, with a thorough review of all code. The main change is that
interface layer has been removed from the CARP. Now redundant addresses
are configured exactly on the interfaces, they run on.

The CARP configuration itself is, as before, configured and read via
SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or
SIOCAIFADDR_IN6 may now be configured to a particular virtual host id,
which makes the prefix redundant.

ifconfig(8) semantics has been changed too: now one doesn't need
to clone carpXX interface, he/she should directly configure a vhid
on a Ethernet interface.

To supply vhid data from the kernel to an application the getifaddrs(8)
function had been changed to pass ifam_data with each address. [1]

The new implementation definitely closes all PRs related to carp(4)
being an interface, and may close several others. It also allows
to run a single redundant IP per interface.

Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for
idea on using ifam_data and for several rounds of reviewing!

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.

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

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.
