+/*
+ * vsockmon is the AF_VSOCK packet capture device. Packets captured have the
+ * following layout:
+ *
+ * +-----------------------------------+
+ * | vsockmon header |
+ * | (struct af_vsockmon_hdr) |
+ * +-----------------------------------+
+ * | transport header |
+ * | (af_vsockmon_hdr->len bytes long) |
+ * +-----------------------------------+
+ * | payload |
+ * | (until end of packet) |
+ * +-----------------------------------+
+ *
+ * The vsockmon header is a transport-independent description of the packet.
+ * It duplicates some of the information from the transport header so that
+ * no transport-specific knowledge is necessary to process packets.
+ *
+ * The transport header is useful for low-level transport-specific packet
+ * analysis. Transport type is given in af_vsockmon_hdr->transport and
+ * transport header length is given in af_vsockmon_hdr->len.
+ *
+ * If af_vsockmon_hdr->op is AF_VSOCK_OP_PAYLOAD then the payload follows the
+ * transport header. Other ops do not have a payload.
