Hi,
We're seeing some issue with the MLX ConnectX 10 Gbps; more specifically, we see some packets getting a VLAN tag from a different flow. Our interface is configured to process tagged and untagged traffic. The symptom is that an untagged packet gets a tag from a nearby packet, thus causing said packet to be ignored by the IP stack (it's not expecting a vlan).
We're using 1.5.10 on the latest Centos6.5 kernel. We know it's a vlan issue, because if we move the tagged traffic to another interface, there are no issues...
We've tried the absolute latest version as well, to no avail.
Really weird issue, hope someone can help. Thanks
