Last change on this file since 52656ed was 52656ed, checked in by Shane Alcock <salcock@…>, 13 years ago
  • Updated autotools to detect DAG 3.X drivers. The new detection method will also catch DAG 2.5, but this is not a problem because the API is the same so DAG 2.5 and DAG 3 can use the same code within libtrace.
  • Changed format_dag25.c to manage the dag stream manually, similar to format_dag24.c.
  • Libtrace programs using DAG 2.5 and greater should now detach the DAG stream properly, provided they are exited cleanly.
  • The snaplen can now be configured for DAG 2.5 and DAG 3.0 inputs
  • Property mode set to 100644
