[ Upstream commit 8f6617badcc96a582678ea36ea96490c5ff26eb4 ]
Port the same fix for ixgbe to ixgbevf.
The ixgbevf driver currently does IPsec Tx offloading based on an existing secpath. However, the secpath can also come from the Rx side, in this case it is misinterpreted for Tx offload and the packets are dropped with a "bad sa_idx" error. Fix this by using the xfrm_offload() function to test for Tx offload.
