EFI IPSEC Protocol Definition
The EFI_IPSEC_PROTOCOL is used to abstract the ability to deal with the individual
packets sent and received by the host and provide packet-level security for IP datagram.

Handles IPsec packet processing for inbound and outbound IP packets.
The EFI_IPSEC_PROCESS process routine handles each inbound or outbound packet.
The behavior is that it can perform one of the following actions:
bypass the packet, discard the packet, or protect the packet.
@param[in] This Pointer to the EFI_IPSEC_PROTOCOL instance.
@param[in] NicHandle Instance of the network interface.
@param[in] IpVer IPV4 or IPV6.
@param[in, out] IpHead Pointer to the IP Header.
@param[in] LastHead The protocol of the next layer to be processed by IPsec.
@param[in] OptionsBuffer Pointer to the options buffer.
@param[in] OptionsLength Length of the options buffer.
@param[in, out] FragmentTable Pointer to a list of fragments.
@param[in] FragmentCount Number of fragments.
@param[in] TrafficDirection Traffic direction.
@param[out] RecycleSignal Event for recycling of resources.
@retval EFI_SUCCESS The packet was bypassed and all buffers remain the same.
@retval EFI_SUCCESS The packet was protected.
@retval EFI_ACCESS_DENIED The packet was discarded.
