statements. Move the setting of the Protocol column in various dissectors before anything is fetched from the packet, and also clear the Info column at that point in those and some other dissectors, so that if an exception is thrown, the columns don't reflect the previous protocol. Make the IP dissector static, as it's called only via dissector tables or dissector handles. Also make the "dissect the TOS field as the DiffServ DS field" flag static, as it's not referred to outside of "packet-ip.c". In the NCP dissector, refer to the port type through "pinfo" rather than through the global "pi", as it's a tvbuffified dissector. svn path=/trunk/; revision=2929
