[j-nsp] QFX10k PFE

I have a 10k8 that's showing "data error" discards in `show pfe 
statistics traffic`.  JTAC gave me the very unhelpful suggestion to run 
packet captures and try and guess what's getting dropped, which isn't 
really something that's feasible to do (nor am I even sure the packets 
would show up there, since they're getting hardware dropped).

I poked around on the FPC console, and found "set pfe monitor 
hw-discard", which seems to be what I want.  Has anyone used this 
before?  I can't seem to find any docs on it, and I'm not sure enabling 
it randomly is really a good idea.
