[j-nsp] [SRX650] show pfe statistics weirdness

[Graham Brown]

Hi Nick,

This is where the SRX platform differs from that of the M/T/MX etc. BFD
processing is NOT offloaded to the PFEs - this is all done by the RE. This
has caused one of my customers many problems and unfortunately is by design
- this relates to the SRX 3600.

HTH,
Graham
