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