[brussels-dev] Support for 'dladm -o..' command

The wf_cmdtype determines which of those fields apply to which dladm
subcommands (currently: neither, show-wifi, scan-wifi, or both).

FWIW, I've implemented generic "-o" support as part of the upcoming
ipmpstat utility.  It's loosely based on the dladm/WiFi stuff but I think
it's ultimately more extensible and flexible.  Please check out:

http://cr.opensolaris.org/~meem/clearview-ipmp/raw_files/new/usr/src/cmd/cmd-inet/usr.sbin/ipmpstat/ipmpstat.c

In particular, you'll want to take a look at the ofmt_* functions, and the
ipmpstat_field_t/ipmpstat_ofmt_t structures.  A block comment at the top
of the file describes the basic workflow (which is a bit complex since
there are two layers of function pointers).
