-/** \r
- @par Protocol Description:\r
- The EFI_SIMPLE_NETWORK_PROTOCOL protocol is used to initialize access \r
- to a network adapter. Once the network adapter initializes, \r
- the EFI_SIMPLE_NETWORK_PROTOCOL protocol provides services that \r
- allow packets to be transmitted and received.\r
- \r
- @param Revision\r
- Revision of the EFI_SIMPLE_NETWORK_PROTOCOL. All future revisions must \r
- be backwards compatible. If a future version is not backwards compatible \r
- it is not the same GUID.\r
-\r
- @param Start\r
- Prepares the network interface for further command operations. \r
- No other EFI_SIMPLE_NETWORK_PROTOCOL interface functions will operate \r
- until this call is made. \r
-\r
- @param Stop\r
- Stops further network interface command processing. \r
- No other EFI_SIMPLE_NETWORK_PROTOCOL interface functions will operate \r
- after this call is made until another Start() call is made. \r
-\r
- @param Initialize\r
- Resets the network adapter and allocates the transmit and receive buffers. \r
-\r
- @param Reset\r
- Resets the network adapter and reinitializes it with the parameters \r
- provided in the previous call to Initialize(). \r
-\r
- @param Shutdown\r
- Resets the network adapter and leaves it in a state safe for another driver \r
- to initialize. The memory buffers assigned in the Initialize() call are released. \r
- After this call, only the Initialize() or Stop() calls may be used. \r
-\r
- @param ReceiveFilters\r
- Enables and disables the receive filters for the network interface and, \r
- if supported, manages the filtered multicast \r
- HW MAC (Hardware Media Access Control) address list. \r
-\r
- @param StationAddress\r
- Modifies or resets the current station address, if supported. \r
-\r
- @param Statistics\r
- Collects statistics from the network interface and allows the statistics to be reset. \r
-\r
- @param MCastIpToMac\r
- Maps a multicast IP address to a multicast HW MAC address. \r
-\r
- @param NvData\r
- Reads and writes the contents of the NVRAM devices attached to the network interface. \r
-\r
- @param GetStatus\r
- Reads the current interrupt status and the list of recycled transmit \r
- buffers from the network interface. \r
-\r
- @param Transmit\r
- Places a packet in the transmit queue. \r
-\r
- @param Receive\r
- Retrieves a packet from the receive queue, along with the status \r
- flags that describe the packet type. \r
-\r
- @param WaitForPacket\r
- Event used with WaitForEvent() to wait for a packet to be received.\r
-\r
- @param Mode\r
- Pointer to the EFI_SIMPLE_NETWORK_MODE data for the device. \r
