Disclaimer: My first patches to Intel drivers, implemented AF_XDP zero-copy feature which seemed to be missing for igb. Not sure if it was a conscious choice to not spend time implementing this for older devices, nevertheless I send them to the list for review. The first couple of patches adds helper funcctions to prepare for AF_XDP zero-copy support which comes in the last couple of patches, one each for Rx and TX paths.
