[ovs-dev] [PATCH v2 0/5] userspace: enable VXLAN TSO, GSO and GRO

[yang_y_yi at 163.com]

From: Yi Yang <yangyi01 at inspur.com>

Many NICs can support VXLAN TSO, this can improve
VM-to-VM TCP performance, but for UDP, most of NICs
can offload UFO, so GSO is very necessary for UDP
when userspace TSO is enabled, GSO also can do
VXLAN TSO if NIC can't support it. GRO is necessary
if TSO and UFO are enabled, it can avoid plenty of
overhead.

This patch series fix all the aforementioned issues.
By the way, GSO and GRO needs DPDK to apply two patches
I have sent out to dev at dpdk.org:
