[net-next,00/15] qed/qede: improve chain API and add XDP_REDIRECT support

Message

Alexander Lobakin July 22, 2020, 3:53 p.m. UTC

This series adds missing XDP_REDIRECT case handling in QLogic Everest
Ethernet driver with all necessary prerequisites and ops.
QEDE Tx relies heavily on chain API, so make sure it is in its best
at first.

Alexander Lobakin (15):
  qed: reformat "qed_chain.h" a bit
  qed: reformat Makefile
  qed: move chain methods to a separate file
  qed: prevent possible double-frees of the chains
  qed: sanitize PBL chains allocation
  qed: move chain initialization inlines next to allocation functions
  qed: simplify initialization of the chains with an external PBL
  qed: simplify chain allocation with init params struct
  qed: add support for different page sizes for chains
  qed: optimize common chain accessors
  qed: introduce qed_chain_get_elem_used{,u32}()
  qede: reformat several structures in "qede.h"
  qede: reformat net_device_ops declarations
  qede: refactor XDP Tx processing
  qede: add .ndo_xdp_xmit() and XDP_REDIRECT support

Netdev folks, could you please take the entire series through your tree
after the necessary acks and reviews? Patches 8-9 also touch qedr driver
under rdma tree, but these changes can't be separated as it would break
incremental buildability and bisecting.
