vmxnet3: correctly report csum_level for encapsulated packet
[ Upstream commit 3d8f2c4269d08f8793e946279dbdf5e972cc4911 ] Commitdacce2be33
("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. Fixes:dacce2be33
