Speeds for Mellanox NICs on BIG-IP Virtual Edition may be reported incorrectly. The behavior varies depending on what driver is in use: - Speeds are always reported as 10G when the mlxvf5 driver is used, regardless of the actual speed of the interface. - Speeds are reported as either 10G or 40G when the xnet driver is used. This is accurate unless the actual NIC speed is greater than 40G, in which is it will still be reported as 40G.


Possibly incorrect media speed reported. (Actual speed is correct, regardless of what is displayed.)
