Re: [Ntop] Unknown DLT types

[Julien TOUCHE]

If you can figure out the data link level header length and the associated
DLT code, you can try adding them to the table in globals-core.c at 380ff:
  _mtuSize[DLT_NULL] = 8232                                    /* no
link-layer encapsulation */;
  _headerSize[DLT_NULL] = CONST_NULL_HDRLEN;
      /* 1500 + 14 bytes header Courtesy of Andreas Pfaller
<[EMAIL PROTECTED]> */
  _mtuSize[DLT_EN10MB] = 1500+sizeof(struct ether_header)      /* Ethernet
(10Mb) */;
  _headerSize[DLT_EN10MB] = sizeof(struct ether_header);
...
tun device i used (openvpn) must have same ethernet header as normal 
ones. i can get mtu from `ifconfig -a` and it depends (have 1500 and 
1255, sit1 is 1480).
for header size, i will ask on openvpn mailing-list.

last interface is sit1 (ipv6 tunnel), but it doesn't matter for now (as 
far as i'm concerned).
