[ Upstream commit f049efc7f7cd2f3c419f55040928eaefb13b3636 ]
The VF driver can forward any IPsec flags and such makes the function is not extendable and prone to backward/forward incompatibility.
If new software runs on VF, it won't know that PF configured something completely different as it "knows" only XFRM_OFFLOAD_INBOUND flag.
