Mmh, exposing it in the GUI is relatively easy, but probably under a "mere mortals need not go here" class of advanced configuration option (like the fully non checked strings passed to the disc lines :)) 
So we need a qualifier> 1000b or 1000p ? and parse that somewhere. Luci can do some simple checking for us but we can not really interact with the user. Is limit really universal for all discs?

	Well, if we select defaults that work well and mark the options so that it is easy to return to the default state we might be golden…?

	We can easily give a short description to each "pfifo: prone to long latencies, avoid" ?

	I have an idea how to expose the output of these command in the guy (pretty raw) polling or parsing the whole and turn it into something nice is out of my capabilities though.

	Well, running RRUL over the 5GHz got me:
