Well, the fact that this patch makes the symptom go away indicates that the= re=20 is some more fundamental problem hiding somewhere in the driver/hardware th= at=20 should get fixed all the way. It is, however, a valid workaround until the= =20 real problem is identified. Can you please submit a PR with the information in this thread? I will loo= k=20 into the driver some more and commit the workaround if I fail to find the=20 real cause soon. EVERYBODY: Could you please check if you have a rl(4) driven NIC and check = if=20 you experienced a speed degradation as well. Please let me know either way= =20 with information about the chipset on your NIC.
