parameter problem

["李敏" <fly.limin () gmail com>]

when I use the command snort -dev -n 1,it shows like this:
===============================================================================

Snort received 7 packets
    Analyzed: 7(100.000%)
    Dropped: 0(0.000%)
===============================================================================
Breakdown by protocol:
    TCP: 1          (14.286%)
    UDP: 0          (0.000%)
   ICMP: 0          (0.000%)
    ARP: 0          (0.000%)
  EAPOL: 0          (0.000%)
   IPv6: 0          (0.000%)
    IPX: 0          (0.000%)
  OTHER: 0          (0.000%)
DISCARD: 0          (0.000%)
===============================================================================

according to the "man snort" ,we can set "-n" to decide how many packets to
process, but it shows snort received 7 packets and analyzed 7,not 1.
since I know it is relative to the pkt_cnt parameter in the source code, but
what it really means?
