"mediaopt"?

You need an additional mechanism for selecting between 11a/b/g on multi-mode
devices.  All such devices have a media of "802.11" and mediaopt isn't
appropriate because it's orthogonal.  The easiest way to see the problem is
to ask how you would specify OFDM at 54Mb/s in the 2.4Ghz range (i.e. 11g).
With the current media and mediaopts you have no way.  With this addition
you specify this by adding "mode 11g".  There's still some issues with "pure
11g" vs "11g" (pure means no 11b rates are supported and you don't have to
worry about supporting both 11b and "purge g" stations on the same AP) but
I'm going to avoid that until my 11g stuff is all committed.
