> UDP/IPv4 GRO can help improve VM-to-VM UDP performance
> when UFO or GSO is enabled in VM, GRO must be supported
> if UFO or GSO is enabled, otherwise, performance can't
> get big improvement if only GSO is there.

> With this enabled in DPDK, OVS DPDK can leverage it
> to improve VM-to-VM UDP performance, it will reassemble
> UDP fragments immediate after they are received from
> a physical NIC. It is very helpful in OVS DPDK VLAN use
> case.
