body: <p>I had used the following command to generate a GTP packet using sendp</p>
  
  <pre><code>&gt;&gt;&gt;sendp(Ether()/IP(dst="1.1.1.1", proto=17,  
  len=124)/UDP(sport=2152,dport=2152,len=104)/Raw(load=('32 ff 00 58 00 00 00 01 '

  <p>Expecting the Data of UDP packet as - </p>
  
  <pre><code>32 ff 00 58 00 00 00 01 28 db 00 00 45 00 00 54 00 00 40 00 40 00 5e a5 ca 0b 28

  <p>But I found this data at "right most side of the packet description", instead of "Middle portion of the packet description".</p>
  
  <p>Could you please let me know the command to be used to correct this.</p>
