* The draft in question has nothing to do with MPLS; clarify that.Guy Harris2010-03-191-54/+65
| | | | | | | | | | | Presumably the idea is that the technique is generally applicable as long as the traffic being carried is either IPv4, IPv6, OSI CLNP, ES-IS, or IS-IS. Also, by the time we get there, we know we've reached the bottom of the MPLS stack (the do loop either fails by running past the end of the packet and going to trunc, or by terminating because we find a label entry with the BOS bit set); there's no need to check for that.
* Print the MPLS-encapsulated packet regardless of whether -v wasGuy Harris2010-03-191-81/+108

* Have the configure script arrange that the Makefile define _U_guy2003-11-161-4/+4
| | | | | | | | | | appropriately, and that GNUmakefile and the MSVC++ project file define it apppriately, as we do with libpcap, rather than defining it in "interface.h". Undo the rcsid-shuffling and addition of extra #includes, as we no longer need to arrange that "interface.h" be included before using _U_ in an RCS ID or copyright.
* From Neil Spring:guy2003-11-151-4/+4
| | | | | | | | | | | use "_U_" in the definitions of "rcsid[]", to eliminate complaints about those variables being unused; move the definitions after the include of "interface.h", or add an include of "interface.h", so that "_U_" is defined. Include "config.h" before including "tcpdump-stdinc.h" in "missing/datalinks.c".
