Libtrace 4.0.29

New features

• Added new API method: trace_construct_packet_zc(), which provides a faster zero-copy method for converting a buffer of packet payload into a libtrace packet, which can replace trace_construct_packet() in very specific situations.

Improvements

• Significant performance improvements for ring: inputs due to moving from tpacket version 2 to version 3.
• Further performance improvements when calling trace_get_layer3() on ring: inputs.
• Improved tracereplay performance.

Bug fixes

• Removed annoying warning messages emitted by DPDK libraries that appeared when using DPDK inputs.
• Fixed outdated XDP eBPF code example.
