Jakub, you wrote "ethtool-next" in subject, but I only managed to apply
the patches to the master branch.

Michal, I assume we are expected to send new features to next? If so,
can you please update the web page [1] ?

Thanks

Indeed, sorry about that. Let me rebase and repost.
Thanks for testing!

That's my fault. When I decided to skip version 5.12 because there were
only few minor commits, I should have merged next into master. I'll do
it tomorrow.

I don't insist on the strict division between fixes and features. The
main purpose of next branch is to queue changes to be merged after the
closest release because their kernel counterpart is in net-next and is
not going to be present in the closest kernel.

On the other hand, I also plan to use it for stuff which feels too
intrusive to be merged into master shortly before a new release. Thanks
for the reminder, I'll review the web page and update the information.

Michal
