Subject: [PATCH iwl-next v2 0/4] igb: Add support for AF_XDP zero-copy

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.

I will attach performance numbers to this thread in a couple of days.

v1->v2:
- Use batch XSK APIs (Maciej Fijalkowski)
- Follow reverse xmas tree convention and remove the ternary operator
  use (Simon Horman)

Sriram Yagnaraman (4):
  igb: prepare for AF_XDP zero-copy support
  igb: Introduce XSK data structures and helpers
  igb: add AF_XDP zero-copy Rx support
  igb: add AF_XDP zero-copy Tx support
