2003-10-01Have a pseudo-header for Ethernet packets, giving the size of the FCS -Guy Harris1-1/+0
0 means "there is no FCS in the packet data", 4 means "there is an FCS in the packet data", -1 means "I don't know whether there's an FCS in the packet data, guess based on the packet size". Assume that Ethernet encapsulated inside other protocols has no FCS, by having the "eth" dissector assume that (and not check for an Ethernet pseudo-header). Have "ethertype()" take an argument giving the FCS size; pass 0 when appropriate. Fix up Wiretap routines to set the pseudo-header. This means we no longer use the "generic" seek-and-read routine, so get rid of it. svn path=/trunk/; revision=8578

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=4323
