Somehow I missed the comment without contact -- when I looked quickly at the code, the xavu is used if contact address is found, being after this piece of code:
``` if(dir==TPS_DIR_DOWNSTREAM) { sv = td->bs_contact; } else { sv = td->as_contact; } if(sv.len<=0) { /* no contact - skip */ return 0; } ```
But I do not use this mode with xavu and don't know what is supposed to do. I just wanted to give some hints.
