[dpdk-users] KNI tcp segmentation offloading

I am using KNI, and I hope the TCP can use segmentation offloading.
However, when I use "ethtool -k vEth0" (the KNI virtual interface), it
tcp-segmentation-offload: off
tx-tcp-segmentation: off [fixed]
tx-tcp-ecn-segmentation: off [fixed]
tx-tcp6-segmentation: off [fixed]

and "sudo ethtool -K vEth0 tso on" gives me:
Cannot change tcp-segmentation-offload
Could not change any device features

Is there a way to enable TCP segmentation offloading with KNI?
