New Module Options
In the elxnet driver, there are two new module parameters:
1. Enable or disable MSI-X support. The driver default is to have MSI-X enabled.
2. Enable or disable vxlan_offload support. The driver default is to have
vxlan_offload enabled.
Note: The following output is for illustrative purposes only. Actual output may vary
depending on the adapter installed in the system.
The server administrator must run the following command to disable MSI-X:
~ # esxcli system module parameters set -p msix=0 -m elxnet
And to verify that the value has been reprogrammed:
~ # esxcli system module parameters list -m elxnet
The output should look similar to the following:
The server administrator must run the following command to disable vxlan_offload:
~ # esxcli system module parameters set -p vxlan_offload=0 -m elxnet
Note: This parameter only applies to OCe14000-series adapters.
And to verify that the value has been reprogrammed:
~ # esxcli system module parameters list -m elxnet
The output should look similar to the following:
