I have seen this issue myself with the 3.0 mlx4_en driver but do not see it anymore with the latest version of this driver. I do not know which patch fixes this issue. But I have been wondering whether it could have been the following patch: commit 0cc5c8bf11852dec3225fda2f53a599243095d23 net/mlx4_en: Fix a race between napi poll function and RX ring cleanup The RX rings were cleaned while there was still possible RX traffic completion handling. Change the sequence of events so that the port is closed and the QPs are being stopped before RX cleanup.
