So to make sure I have this right... mixed data happens when there is packet
loss.  Turning on "zero_flushed_packets" will prevent the mixing, causing me
to see all 0x00 instead.

If running "zero_flushed_packets" has a performance hit associated, won't it
increase incidence of dropped packets, and make the reassembly problem even
worse?

Thanks for the info so far guys, keep it coming =)
