Opened: Feb 19, 2020

Severity: 3-Major


In some unsupported environments, the underlying sock driver uses only only 1 queue. You can confirm whether it does so by executing the tmctl command to check the rxq column (which shows 0): tmctl -d blade -i tmm/ndal_rx_stats' and You can verify this on the tx side as well.


When multi-q is present, the use of single queue can impact performance when using the sock driver.


This occurs in certain unsupported environments. Note: When you run 'ethtool -l', you can see: 'command not supported'.


Use other available drivers. You can check the available drivers by executing the tmctl command: tmctl -d blade -i tmm/device_probed
