net/mlx5e: Do not recover from a non-fatal syndrome
|
|
|
|
For non-fatal syndromes like LOCAL_LENGTH_ERR, recovery shouldn't be
|
|
triggered. In these scenarios, the RQ is not actually in ERR state.
|
|
This misleads the recovery flow which assumes that the RQ is really in
|
|
error state and no more completions arrive, causing crashes on bad page
|
|
state.
|
|
|
|
Fixes: 8276ea1353a4 ("net/mlx5e: Report and recover from CQE with error on RQ")
