title: Why Packet drop is not captured under ifconfig?
body: <p>I have provided below lines in order to simulate the packet drop on my Linux box.</p>
  
  <pre><code># for randomly dropping 10% of incoming packets:
  iptables -A INPUT -m statistic --mode random --probability 0.1 -j DROP
  
  # and for dropping 10% of outgoing packets:
  iptables -A OUTPUT -m statistic --mode random --probability 0.1 -j DROP
  </code></pre>
  
  <p>After that I run ping some_ip_address and when I terminate it ,can see line </p>
  
  <pre><code>100 packets transmitted, 84 received, 16% packet loss, time 99137ms
  </code></pre>
  
  <p>But when I run the ifconfig command I see packet drop filled is still zero</p>
  
  <pre><code>      RX packets:16007 errors:0 dropped:0 overruns:0 frame:0
        TX packets:16207 errors:0 dropped:0 overruns:0 carrier:0
        collisions:0 txqueuelen:1000
  </code></pre>
  
  <p>Here, you  can see Dropped field in Rx and Tx packet row is still Zero.</p>
  
  <p>Can any body let me know why packet loss didn't capture under ifconfig?</p>
