Is this a general requirement or something specific to ixgbe/i40e? FWIW, vmxnet3 device does not support tx IP checksum offload but doe support TSO. In that case, we cannot leave IP checksum field as 0 (the correct checksum needs to be filled in the header) before passing it the the NIC when TSO is enabled.
