Various mlx5 bugs on eBPF refcount handling found during review. Last patch in series adds a __must_check to BPF helpers to make sure we won't run into it again w/o compiler complaining first.
v1 -> v2: - After discussion with Alexei, we agreed upon rebasing the patches against net-next. - Since net-next, I've also added the __must_check to enforce future users to check for errors. - Fixed up commit message #2. - Simplify assignment from patch #1 based on Saeed's feedback on previous set. Thanks a lot!
