[j-nsp] Difference MX DPC-R / DPCE-R

Your Juniper SE could provide details. My guess is that is has to do
with the chipset, specifics of which I don't know. Given the naming
convention of the M series FPC for example, M320-FPC2-E2 (LMNR) vs.
the E3 (I-Chip), it stands to reason that Juniper would follow a
simliar convention with the MX series cards.
