[Kernel-packages] [Bug 1967754] Re: ubuntu 22.04 jammy, mlx5, can't change flow steering mode

2022-04-29 Thread dann frazier 
We decided the best approach was to revert the break patch which is now
done in 5.15.y upstream:

commit f1607e13ed715f3b6433361f8ea5d4aa79f03b94
Author: dann frazier 
Date:   Thu Apr 7 14:16:42 2022 -0600

Revert "net/mlx5: Accept devlink user input after driver
initialization complete"

Which was released in v5.15.34, and is being tracked for jammy inclusion
in bug 1969107.

2022-04-05 Thread dann frazier 
@Amir: if that fixes the problem for you, would you mind submitting it
to sta...@vger.kernel.org? I've verified that stable 5.15.y is impacted,
which is where Ubuntu inherited it from. I also tested upstream 5.15.y
w/ cf530217408e applied, and it does seem to fix this issue.

[Kernel-packages] [Bug 1967754] Re: ubuntu 22.04 jammy, mlx5, can't change flow steering mode

2022-04-04 Thread Amir Tzin 
https://lore.kernel.org/netdev/cover.1632565508.git.leo...@nvidia.com/

It seems jammy kernel needs cf530217408e ("devlink: Notify users when objects 
are accessible") from v5.16-rc1
(see link) the old  devlink_register (before cf530217408e) implementation do 
not publish the params so we cannot erase the calls to devlink_params_publish. 
i'll update once finished testing with cf530217408e ported.
