Anyone knows how to turn off TSO in DPDK+SR-IOV in KVM guest VM ? I want
the packets sending out of the KVM host not to have TSO by the hardware.

I imagine that I need to do the following:
1. turn off TSO in the guest before starting DPDK using ethtool -K ethX tso
off
    After DPDK is started, the device will be removed.
    I think the command ethtool will call ethtool function in the
ixgbevf.ko in the kernel to turn TSO off. Am I correct ?
2. turn off TSO on the host using ethtool -K ethX tso off

Do I need to do the second one ? Would the first one propagate down to the
host ?

Please ignore this post. I re-post it with the right subject. Sorry about
this.
