> The ixgbe 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.
