Enable TSO support on the network adapter of a Linux virtual machine so that the guest operating system redirects TCP packets that need segmentation to the VMkernel.

Before you begin

  • Verify that ESXi 6.0 supports the Linux guest operating system.

    See the VMware Compatibility Guide documentation.

  • Verify that the network adapter on the Linux virtual machine is VMXNET2 or VMXNET3.

Procedure

In a terminal window on the Linux guest operating system, to enable or disable TSO, run the ethtool command with the -K and tso options.
  • To enable TSO, run the following command:

    ethtool -K ethY tso on
  • To disable TSO, run the following command:

    ethtool -K ethY tso off

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