[Fix]
the root cause for this error is canceling uninitialized delayed_work_queue belongs to ipoib net devices and the solution is not failing to initialize it.
this solution is specified in the very small patched (one line) attached.
please note that this patch is not upstream and it is based on the following upstream commits which introduced similar functionality to upstream v4.20-rc1.
303211b44ce3 net/mlx5e: Always initialize update stats delayed work
182570b26223 net/mlx5e: Gather common netdev init/cleanup functionality in one place
applying this two on the bionic tree in a clean way requires more patches that might introduce a large change so I think it's better (if possible) to use the attached patch.
[Regression Potential]
Regression risk is low since it's introduce a small fix that was also accepted upstream in v4.20. |

[Fix]
the root cause for this error is canceling uninitialized delayed_work_queue belongs to ipoib net devices and the solution is not failing to initialize it.
this solution is specified in the very small patched (one line) attached.
please note that this patch is not upstream and it is based on the following upstream commits which introduced similar functionality to upstream v4.20-rc1.
303211b44ce3 net/mlx5e: Always initialize update stats delayed work
182570b26223 net/mlx5e: Gather common netdev init/cleanup functionality in one place
applying this two on the bionic tree in a clean way requires more patches that might introduce a large change so I think it's better (if possible) to use the attached patch.
[Regression Potential]
Regression risk is low since it's introduce a small fix that was also accepted upstream in v4.20. |
