[PATCH net-next 0/9][pull request] 1GbE Intel Wired LAN Driver Updates 2021-04-09

[Tony Nguyen <anthony.l.nguyen@intel.com>]

This series contains updates to igc driver only.

Andre Guedes says:

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.

The following are changes since commit 4438669eb703d1a7416c2b19a8a15b0400b36738:
