ixgbe: fail to create xfrm offload of IPsec tunnel mode SA
Based on talks and indirect references ixgbe IPsec offlod do not
support IPsec tunnel mode offload. It can only support IPsec transport
mode offload. Now explicitly fail when creating non transport mode SA
with offload to avoid false performance expectations.
Fixes: 63a67fe229ea ("ixgbe: add ipsec offload add and remove SA")
