Check your buffer size and util.  No buffer space and it must drop

I'm using cacti for graphing traffic and such - but that doesn't give
me a look into the upper layer traffic (what is doing what).

About to open a TAC case as it is, trying to figure out why we're
seeing so many "Discards In" and no other counter really increasing
(with the exception of the occasional Discards Out blip)....

Will check out NBAR.
