o check the channel list returned in the devcaps to identify whether a
device supports 1/2 or 1/4 width channels on a band; this might be
better brought out as a capability bit to avoid filling the channel

right now we don't check frequency range only band)
o change ioctl's that pass channel lists in/out to handle variable-size

to return > IEEE80211_CHAN_MAX entries for calls like IEEE80211_IOC_DEVCAPS

can lead to ill side effects. One such effect found is as follows:
"kldunload if_foo" tells the module to kill all its interfaces,

devd starts processing the messages, which ends up in a etc script
running ifconfig fooX, which reloads the module.

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?).

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.
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
