c871174916 Use strlcpy() instead of strncpy() when copying ifname to ensure
that it is NUL terminated.  Additional NUL padding is not required
for short names.

Use sizeof(destination) in a few places instead of IFNAMSIZ.

Cast afp->af_ridreq and afp->af_addreq  to make the intent of
the code more obvious.

eb7e25b22f ifmedia changes:
- Extend the number of available subtypes for Ethernet media by using some
of the ifmedia word's option bits to help denote subtypes. As a result, the
number of possible Ethernet subtype values increases from 31 to 511.

- Use some of those new values to define new media types.

- lacp_compose_key() recgonizes the new Ethernet media types added.
  (Change made as required by a comment in if_media.h)

- New ioctl, SIOGIFXMEDIA, to handle getting the new extended media types.
  SIOCGIFMEDIA is retained for backwards compatibility.

- Changes to ifconfig to allow it to handle the new extended media types.

6f135a7584 When setting media always and not just in case of switching to IFM_AUTO
clear the options of the current media, i.e. only inherit the instance,
which matches what NetBSD does. Without this it's really non-intuitive
that the following sequence:
	ifconfig bge0 media 1000baseT mediaopt full-duplex
	ifconfig bge0 media 100baseTX
results in 100baseTX full-duplex to be set or that:
	ifconfig bge0 media autoselect mediaopt flowcontrol
	ifconfig bge0 media 1000baseT mediaopt full-duplex
tries to set 1000baseT full-duplex with flowcontrol, which isn't suported
und thus fails while the following:
	ifconfig re0 media 1000baseT mediaopt flowcontrol,full-duplex
	ifconfig re0 media autoselect
just switches to autoselection without flowcontrol.

a84e1b3b24 When printing media with more than one media option set aggregate these

This matches how the options of the active media are printed with

59aa14a91d Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

More information at: http://wiki.freebsd.org/WifiMesh

Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.

Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral).  Also there
no longer are separate wlan_scan* modules; this functionality is now

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

1113949379 - Display the media instance numbers and allow the user to set the active
one. This is based on NetBSD but unlike NetBSD this implementation prints
  the instance number for all media instances and doesn't skip it for the
  first one as I don't see a reason to suppress it except for the vague
  reason to preserve the output for single-instance configurations.
- Fix some whitespace nits.

499e862cae Change the ifr_media operation to only get its value and only set
its value once per ifconfig run.  Use Sam's new callback
operation to set it when everything is done.

The purpose for this is that if you did something like
	ifconfig bge0 media 100baseTX mediaopt full-duplex
multiple times it would end up causing the PHY to re-sync
since it would send the IOCTLs:
	ifconfig bge0 media 100baseTX -mediaopt full-duplex
	ifconfig bge0 media 100baseTX mediaopt full-duplex
This would cause the PHY to be updated twice even though
there really wasn't any change since the check in
sys/net/if_media.c would always fail.

Caveat is that this doesn't fix the case of:
	ifconfig bge0 media autoselect
etc. since in sys/net/if_media.c it forces an autoselect to go through
the entire process in ifmedia_ioctl :-( :
          /*
           * If no change, we're done.
           * XXX Automedia may invole software intervention.
           *     Keep going in case the the connected media changed.
           *     Similarly, if best match changed (kernel debugger?).
           */
           if ((IFM_SUBTYPE(newmedia) != IFM_AUTO) &&
                (newmedia == ifm->ifm_media) &&
                (match == ifm->ifm_cur))
                     return 0;

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
