[Intel-wired-lan] [PATCH 00/10] igc: Add support for AF_XDP zero-copy

[Andre Guedes <andre.guedes@intel.com>]

Hi,

This series adds AF_XDP zero-copy feature to igc driver.

The initial patches do some code refactoring, preparing the code base to
land the AF_XDP zero-copy feature, avoiding code duplications. The last
patches of the series are the ones implementing the feature.

The last patch which indeed implements AF_XDP zero-copy support was
originally way too lengthy so, for the sake of code review, I broke it
up into two patches: one adding support for the RX functionality and the
other one adding TX support. Feel free to squash those two patches when
pushing the series to net-next if you find appropriate.

Best,
Andre
