elliptic low pass enabled on SR2 longitudinal damping
At around 2015-06-06 2:30-ish UTC, I enabled an elliptic low pass filter in the top stage longitudinal damping loop in the SR2 suspension, at FM10. This is something we meant to enable all the time (alog 18694) but somehow got disabled a couple of days ago for some reason. I updated the SDF accordingly. So fat the SR2 suspension looks behaving fine.
