XDP for idpf is currently 5 chapters:
* convert Rx to libeth;
* convert Tx completion and stats to libeth (this);
* generic XDP and XSk code changes;
* actual XDP for idpf via libeth_xdp;
* XSk for idpf (^).
Part II does the following:
* introduces generic libeth per-queue stats infra;
* adds generic libeth Tx completion routines;
* converts idpf to use generic libeth Tx comp routines;
* fixes Tx queue timeouts and robustifies Tx completion in general;
* fixes Tx event/descriptor flushes (writebacks);
* fully switches idpf per-queue stats to libeth.
Most idpf patches again remove more lines than adds.
The perf difference is not visible by eye in common scenarios, but
the stats are now more complete and reliable, and also survive
ifups-ifdowns.
Alexander Lobakin (6):
unroll: add generic loop unroll helpers
libeth: add common queue stats
libie: add Tx buffer completion helpers
idpf: convert to libie Tx buffer completion
netdevice: add netdev_tx_reset_subqueue() shorthand
idpf: switch to libeth generic statistics
Joshua Hay (2):
idpf: refactor Tx completion routines
idpf: enable WB_ON_ITR
Michal Kubiak (1):
idpf: fix netdev Tx queue stop/wake
