For the most part, driver specific parameters are evil and shouldn't be
used.  What's fixed_freq again?  Does that force the device onto a
single frequency and disable IBSS merging?  Perhaps instead of using
"fixed_freq", which seems to overlap a lot with the existing 'frequency'
config item, you could just have an option to disable IBSS merging if
it's supported by the driver?  It's obviously just a hint, since not all
devices (even ones that support cfg80211) support disabling IBSS
merging.
