Description
Currently by default the ifaces are initialized with these default/expected offloading:
https://github.com/DUNE-DAQ/dpdklibs/blob/8756f22481c1a376dfb0762defc9a489e7f8f5e1/include/dpdklibs/EALSetup.hpp#L40
This might not be available on every NIC (e.g.: 10Gb interfaces).
Problem was reported during the testing with Intel X722 10Gb OCP NIC at the 50L prototype.
We need to find a way to:
- Identify offloading capabilities of the interface
- Enable/use available offloading capabilities specified in configuration
- Throw issues accordingly: error on configured/expected but not available, or introduce "enable if available" options.
