Subject: [PATCH v7 intel-next 0/9] XDP_TX improvements for ice

I didn't realize that on v6 I didn't have CONFIG_NET_SWITCHDEV option
set in the kernel config. I removed ice_eswitch_remap_ring but didn't
adjust the q_vector's ring pointer to the new Rx/Tx union.

Hope that it's the last time of embarrassment :)

v6->v7:
* fix compilation issues when CONFIG_NET_SWITCHDEV=y

v5->v6:
* rebase set on Tony's dev-queue
* adjust switchdev code to ring split
* compile with W=1 C=2 and fix outstanding kdoc issues

v4->v5:
* fix issues pointed by lkp; variables used for updating ring stats
  could be un-inited
* s/ice_ring/ice_rx_ring; it looks now symmetric given that we have
  ice_tx_ring struct dedicated for Tx ring
* go through the code and use ice_for_each_* macros; it was spotted by
  Brett that there was a place around that code that this set is
  touching that was not using the ice_for_each_txq. Turned out that there
  were more such places
* take care of coalesce related code; carry the info about type of ring
  container in ice_ring_container
* pull out getting rid of @ring_active onto separate patch, as suggested
  by Brett

v3->v4:
* fix lkp issues;

v2->v3:
* improve XDP_TX in a proper way
* split ice_ring
* propagate XDP ring pointer to Rx ring

v1->v2:
* try to improve XDP_TX processing

v6 : https://lore.kernel.org/bpf/20210818135916.25007-1-maciej.fijalkowski@intel.com/
v5 : https://lore.kernel.org/bpf/20210818075256.GA16780@ranger.igk.intel.com/
v4 : https://lore.kernel.org/bpf/20210806095539.34423-1-maciej.fijalkowski@intel.com/
v3 : https://lore.kernel.org/bpf/20210805230046.28715-1-maciej.fijalkowski@intel.com/
v2 : https://lore.kernel.org/bpf/20210705164338.58313-1-maciej.fijalkowski@intel.com/
v1 : https://lore.kernel.org/bpf/20210601113236.42651-1-maciej.fijalkowski@intel.com/

Thanks!

Maciej Fijalkowski (9):
  ice: remove ring_active from ice_ring
  ice: move ice_container_type onto ice_ring_container
  ice: split ice_ring onto Tx/Rx separate structs
  ice: unify xdp_rings accesses
  ice: do not create xdp_frame on XDP_TX
  ice: propagate xdp_ring onto rx_ring
  ice: optimize XDP_TX workloads
  ice: introduce XDP_TX fallback path
  ice: make use of ice_for_each_* macros
