Severity: 3-Major

Symptoms

The Mellanox CX5 Ex adapter is not supported by the BIG-IP with a tmm embedded SR-IOV network driver.

Impact

Systems using a CX5 Ex adapter will have to use the sock driver rather than the Mellanox driver.

Conditions

A BIG-IP Virtual Edition system configured to use one or more Mellanox CX5 Ex adapters in SR-IOV mode.

Workaround

None

Fix Information

Added the CX5 Ex device ID to the BIG-IP's Mellanox SR-IOV driver so that it can be used with that adapter.
