If so, it should be commited as Vladimir as the author, and Vladimir's sign-off should appear before yours. When sending out such patches, there should be a From: line for Vladimir as the first line in the body of the patch email. The same goes for the next mv88e6xxx patch in this series - I think both of these are the patches Vladimir sent in his email: https://lore.kernel.org/r/20220408123101.p33jpynhqo67hebe@skbuf Thanks.

I wasn't sure on how to send those commits, but I guess if I just set the commit author correctly it should be fine. regarding the order: I thought I did it correctly doing bottom up but I confused the order, wasn't on purpose. Sorry about that. I'll resend after verifying all the authors and sign-offs are correct. > > The same goes for the next mv88e6xxx patch in this series - I think > both of these are the patches Vladimir sent in his email: > > https://lore.kernel.org/r/20220408123101.p33jpynhqo67hebe@skbuf > > Thanks. > > -- > RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ > FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last! Thanks for pointing it out! Jakob

Please, do wait at least 24h before reposting, as pointed out in the documentation: https://elixir.bootlin.com/linux/v5.18-rc2/source/Documentation/process/maintainer-netdev.rst#L148 Thanks, Paolo
