title: Wireshark dissector with pcapng format file - access section/interface description fields
body: <p>I am writing a custom protocol wireshark dissector in C as a plugin. I have got the dissector working . I am not able to figure out if there is a way to access the information we fill in section header / interface description header from our dissector? There seem to be tvbuff and packet_info passed , which dont have this information.</p>
  
  <p>Is there a way to access these fields?</p>
