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.
[in] | This | Pointer to the EFI_IPSEC2_PROTOCOL instance. |
[in] | NicHandle | Instance of the network interface. |
[in] | IpVersion | IPV4 or IPV6. |
[in,out] | IpHead | Pointer to the IP Header. |
[in,out] | LastHead | The protocol of the next layer to be processed by IPsec. |
[in,out] | OptionsBuffer | Pointer to the options buffer. |
[in,out] | OptionsLength | Length of the options buffer. |
[in,out] | FragmentTable | Pointer to a list of fragments. |
[in,out] | FragmentCount | Number of fragments. |
[in] | TrafficDirection | Traffic direction. |
[out] | RecycleSignal | Event for recycling of resources. |
EFI_SUCCESS | The packet was bypassed and all buffers remain the same. | |
EFI_SUCCESS | The packet was protected. | |
EFI_ACCESS_DENIED | The packet was discarded. |
