If LRO is enabled for VMXNET3 adapters on the host, activate LRO support on a network adapter on a Linux virtual machine to ensure that the guest operating system does not spend resources to aggregate incoming packets into larger buffers.

Verify that the Linux kernel is 2.6.24 and later.

In a terminal window on the Linux guest operating system, run the ethtool command with the -K and lro options.

To enable LRO, run the following command:

ethtool -K ethY lro on

where Y in ethY is the sequence number of the NIC in the virtual machine.

To disable LRO, run the following command:

ethtool -K ethY lro off

where Y in ethY is the sequence number of the NIC in the virtual machine.
