------- Comment #2 from guy@xxxxxxxxxxxx  2007-08-18 20:59 GMT -------
This will only work if the pcap-format files *have* a direction indicator in
them.  Currently, it doesn't appear that the top-of-tree version of libpcap
puts a direction indicator into the file; if Wireshark is going to expect one
to be there, then libpcap needs to be changed to put one there.

>From looking at bt_read_linux() in libpcap's pcap-bt-linux.c, it appears that
it does get a direction indication:

        /* get direction and timestamp*/
        cmsg = CMSG_FIRSTHDR(&msg);
        while (cmsg) {
                int in;
                switch (cmsg->cmsg_type) {
                        case HCI_CMSG_DIR:
                                in = *((int *) CMSG_DATA(cmsg));
                                break;
                        case HCI_CMSG_TSTAMP:
                                pkth.ts = *((struct timeval *)
CMSG_DATA(cmsg));
                                break;
                }
                cmsg = CMSG_NXTHDR(&msg, cmsg);
        }

Can the value of "in" be used to set a flag in the header?

And should the direction be put in the H4 header, or put into a separate field
added before the header?
