Hello,

this patchset contains second and third parts of another big patchset
for MSG_ZEROCOPY flag support:
https://lore.kernel.org/netdev/20230701063947.3422088-1-AVKrasnov@xxxxxxxxxxxxxx/

During review of this series, Stefano Garzarella <sgarzare@xxxxxxxxxx>
suggested to split it for three parts to simplify review and merging:

1) virtio and vhost updates (for fragged skbs) (merged to net-next, see
link below)
2) AF_VSOCK updates (allows to enable MSG_ZEROCOPY mode and read
tx completions) and update for Documentation/. <-- this patchset
3) Updates for tests and utils. <-- this patchset

Part 1) was merged:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=71b263e79370348349553ecdf46f4a69eb436dc7

Thanks for the series.
I did a quick review highlighting some things that need to be changed.

Overall, the series seems to be in good shape. The tests went well.

In the next few days I'll see if I can get a better look at the larger patches like the tests, or I'll check in the next version.

Thanks,
Stefano
