            I am currently adding a capture engine to sniff i2c traffic. 


I am currently adding this code into Linux using the pcap_linux mechanism (like Bluetooth and USB).


My question is (and I am not currently sure if it’s Wireshark or libpcap) why do I get calls to my function xx_open_live each seconds (approx) during my capture.  


I get calls to the function xx_read to get the packets but I was expecting a call to the xx_open_live function only once when the capture starts and a call to the function xx_close at the end.  My monitoring external hardware cannot be start and stop without loosing packets.


Thanks for your help!
