personally, I don't think this is good enough. The gadget speed is
actually the min() of the f_* speeds. So, IMHO this should be coming
from f_* and during bind you would:
gadget->speed = min(f->speed, gadget->speed);
for all functions. Also, both this patch and what I described above,
only works considering nobody touches that enum, so we might want to be
careful and add some comments to the enum to avoid anyone from touching
