4.0.1-hotfixes, cachetimestamps, develop, dpdk-ndag, etsilive, getfragoff, help, libtrace4, master, ndag_format, pfring, rc-4.0.1, rc-4.0.2, rc-4.0.3, rc-4.0.4, ringdecrementfix, ringperformance, ringtimestampfixes
  • A very cut-down version of int: and ring: is now built on non-Linux systems, enabling them to be able to decode packets captured using those formats and exported via RT
  • Replaced arphrd.h with a new header file (libtrace_arphrd.h) that provides our own #defines for the various ARPHRD types. The inconsistency between what is available on different OS's was becoming problematic.
  • Increased RT buffer size so we can always fit a complete libtrace buffer into it - int: over RT tends to result in very large "packets".
  • Fixed copy-paste error in the failure case when creating a dummy linux trace in format_rt.c
  • Updated various bits of code to use the new LIBTRACE_ARPHRD types where sensible
  • Removed unneeded #include in protocols_pktmeta.c
  • Replaced u32 and u16 types in format_linux with more portable uint32_t and uint16_t types
  • Removed unneeded calls to linuxnative_init_input in the prepare_packet functions in format_linux.c
  • Don't call the fin_input function on a trace if the format does not provide one
