====================
idpf: XDP chapter I: convert Rx to libeth
Alexander Lobakin says:
XDP for idpf is currently 5 chapters:
* convert Rx to libeth (this);
* convert Tx and stats to libeth;
* generic XDP and XSk code changes, libeth_xdp;
* actual XDP for idpf via libeth_xdp;
* XSk for idpf (^).
Part I does the following:
* splits &idpf_queue into 4 (RQ, SQ, FQ, CQ) and puts them on a diet;
* ensures optimal cacheline placement, strictly asserts CL sizes;
* moves currently unused/dead singleq mode out of line;
* reuses libeth's Rx ptype definitions and helpers;
* uses libeth's Rx buffer management for both header and payload;
* eliminates memcpy()s and coherent DMA uses on hotpath, uses
napi_build_skb() instead of in-place short skb allocation.
Most idpf patches, except for the queue split, removes more lines
than adds.
Expect far better memory utilization and +5-8% on Rx depending on
the case (+17% on skb XDP_DROP :>).
* '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
idpf: use libeth Rx buffer management for payload buffer
idpf: convert header split mode to libeth + napi_build_skb()
libeth: support different types of buffers for Rx
idpf: remove legacy Page Pool Ethtool stats
idpf: reuse libeth's definitions of parsed ptype structures
idpf: compile singleq code only under default-n CONFIG_IDPF_SINGLEQ
idpf: merge singleq and splitq &net_device_ops
idpf: strictly assert cachelines of queue and queue vector structures
idpf: avoid bloating &idpf_q_vector with big %NR_CPUS
idpf: split &idpf_queue into 4 strictly-typed queue structures
idpf: stop using macros for accessing queue descriptors
libeth: add cacheline / struct layout assertion helpers
page_pool: use __cacheline_group_{begin, end}_aligned()
cache: add __cacheline_group_{begin, end}_aligned() (+ couple more)
