[ Upstream commit 3d8f2c4269d08f8793e946279dbdf5e972cc4911 ]
Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload
support") added support for encapsulation offload. However, the
pathc did not report correctly the csum_level for encapsulated packet.
This patch fixes this issue by reporting correct csum level for the
encapsulated packet.
