- * For captures on Linux cooked sockets, we construct a fake header
- * that includes:
- *
- * a 2-byte "packet type" which is one of:
- *
- * LINUX_SLL_HOST packet was sent to us
- * LINUX_SLL_BROADCAST packet was broadcast
- * LINUX_SLL_MULTICAST packet was multicast
- * LINUX_SLL_OTHERHOST packet was sent to somebody else
- * LINUX_SLL_OUTGOING packet was sent *by* us;
- *
- * a 2-byte Ethernet protocol field;
- *
- * a 2-byte link-layer type;
- *
- * a 2-byte link-layer address length;
- *
- * an 8-byte source link-layer address, whose actual length is
- * specified by the previous value.
- *
- * All fields except for the link-layer address are in network byte order.
- *
- * DO NOT change the layout of this structure, or change any of the
- * LINUX_SLL_ values below. If you must change the link-layer header
- * for a "cooked" Linux capture, introduce a new DLT_ type (ask
- * "tcpdump-workers@lists.tcpdump.org" for one, so that you don't give it
- * a value that collides with a value already being used), and use the
- * new header in captures of that type, so that programs that can
- * handle DLT_LINUX_SLL captures will continue to handle them correctly
- * without any change, and so that capture files with different headers
- * can be told apart and programs that read them can dissect the
- * packets in them.
