We found that enabling UDP checksums for vxlan triggers GRO on the

want this fix to appear in 3.x upstream kernels, and the corresponding
userspace change in OVS 2.3.
Sorry, this isn't going to happen. Neither the upstream kernel nor OVS
backport features to already released versions.
OVS 2.4 has been released with this feature and is packaged with a
kernel module of backports. Please just use that - considering that
you'd have to make changes all the way up the stack, I don't think
it's any more disruptive.
We cannot change the base distribution - we are using RHEL 7 (3.x
based).
So, you are suggesting to use OVS 2.4 userspace components, and
build the openvswitch kernel-module
shipped with OVS 2.4 along with its dependencies (vxlan, etc) also
shipped
with OVS 2.4 against the RHEL 7.1 (3.x kernel) - and not use any of
the
upstream components for openvswitch, vxlan etc ?
