Most applications won't detect PPP frames if the link type is DLT_CHDLC. This patch makes the DAG capture code check the first frame received and sets the link type to DLT_PPP_SERIAL (full HDLC header) if appropriate.
Checked in.You might want to have "dag_get_datalink()" fill in the error string, rather than doing it in "dag_open_live()" if "dag_get_datalink()" returns -1 - that way, it can put the DAG linktype value into the error message it returns (so that it'll show up in, for example, the error message window in Ethereal).
