files to get that big. From Thomas Wittwer and Matthias Nyffenegger: Support for "ring buffer mode", wherein there's a ring buffer of N capture files; as each capture file reaches its maximum size (the ring buffer works only with a maximum capture file size specified), Ethereal rolls over to the next capture file in the ring buffer, replacing whatever packets might be in it with new packets. svn path=/trunk/; revision=4324
