Yeah, I'm not going to get into the legality of "creating BSD licensed versions of gpl-only Linux apis" but note, lots of lawyers look longingly at those things when they consider early retirement :) > > I thought we already discussed this, AND I talked to someone who > > discussed this with a nvidia lawyer already and I thought this was going > > to get changed.

Ah, missed that, sorry, I didn't see it in the changes for this set of patches, it was in the previous submission. > The summary I have of the call you refer to does not include a > discussion or agreement about change in nvidia policy regarding mlx5 > code. > > Like Dave said, our lawyers are not your lawyers.

I think everyone involved is thankful that your lawyers are not mine :) Ok, best of luck with this mess, I'll stop harping on it now and just point out all of the other issues here. First off, you all need to get the network maintainers to agree that this driver is ok to do this way, and I don't think that has happened yet, so I'll wait on reviewing the series until that is resolved. thanks, greg k-h
