-  returned in DriverName, and EFI_SUCCESS is returned. If the driver specified

-  by This does not support the language specified by Language,

-  then EFI_UNSUPPORTED is returned.

-

-  @param  This[in]              A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or

-Serial Output: Functional on real hardware.

-

-Operating Modes: Currently the user is able to change all operating modes

-except timeout and FIFO depth.

-The default operating mode is:

-	Baudrate:     115200

-	Parity:       None

-	Flow Control: None

-	Data Bits:    8

-	Stop Bits:    1

-Notes: 

-	Data Bits setting of 6,7,8 can not be combined with a Stop Bits setting of 1.5

-

-        At baudrates less than 9600 some of the characters may be transmitted incorrectly.

-

-=== COMPATIBILITY ===

-

-Tested with:

-An FTDI8U232AM based USB-To-Serial adapter, the UEFI Shell, and the SerialTest application 

-using a PuTTY Terminal

-  Attempt to receive a packet from the network adapter.

-

-  This function retrieves one packet from the receive queue of the network

-  interface.  If there are no packets on the receive queue, then EFI_NOT_READY

-  will be returned.  If there is a packet on the receive queue, and the size

-  of the packet is smaller than BufferSize, then the contents of the packet

-  will be placed in Buffer, and BufferSize will be udpated with the actual

-  size of the packet.  In addition, if SrcAddr, DestAddr, and Protocol are

-  not NULL, then these values will be extracted from the media header and

-  returned.  If BufferSize is smaller than the received packet, then the

-  size of the receive packet will be placed in BufferSize and

-  EFI_BUFFER_TOO_SMALL will be returned.

-

-  This routine calls ::Ax88772Rx to update the media status and

-  empty the network adapter of receive packets.

-

-  @param [in] pSimpleNetwork    Protocol instance pointer

-  @param [out] pHeaderSize      The size, in bytes, of the media header to be filled in by

-                                the Transmit() function.  If HeaderSize is non-zero, then

-                                it must be equal to SimpleNetwork->Mode->MediaHeaderSize

-                                and DestAddr and Protocol parameters must not be NULL.

-  @param [out] pBufferSize      The size, in bytes, of the entire packet (media header and

-                                data) to be transmitted through the network interface.

-  @param [out] pBuffer          A pointer to the packet (media header followed by data) to

-                                to be transmitted.  This parameter can not be NULL.  If

-                                HeaderSize is zero, then the media header is Buffer must

-                                already be filled in by the caller.  If HeaderSize is nonzero,

-                                then the media header will be filled in by the Transmit()

-                                function.

-  @param [out] pSrcAddr         The source HW MAC address.  If HeaderSize is zero, then

-                                this parameter is ignored.  If HeaderSize is nonzero and

-                                SrcAddr is NULL, then SimpleNetwork->Mode->CurrentAddress

-                                is used for the source HW MAC address.

-  @param [out] pDestAddr        The destination HW MAC address.  If HeaderSize is zero, then

-                                this parameter is ignored.

-  @param [out] pProtocol        The type of header to build.  If HeaderSize is zero, then

-                                this parameter is ignored.

-  This function is used to enable and disable the hardware and software receive

-  filters for the underlying network device.

-

-  The receive filter change is broken down into three steps:

-

-    1.  The filter mask bits that are set (ON) in the Enable parameter

-        are added to the current receive filter settings.

-

-    2.  The filter mask bits that are set (ON) in the Disable parameter

-        are subtracted from the updated receive filter settins.

-

-    3.  If the resulting filter settigns is not supported by the hardware

-        a more liberal setting is selected.

-

-  If the same bits are set in the Enable and Disable parameters, then the bits

-  in the Disable parameter takes precedence.

-

-  If the ResetMCastFilter parameter is TRUE, then the multicast address list

-  filter is disabled (irregardless of what other multicast bits are set in

-  the enable and Disable parameters).  The SNP->Mode->MCastFilterCount field

-  is set to zero.  The SNP->Mode->MCastFilter contents are undefined.

-

-  After enableing or disabling receive filter settings, software should

-  verify the new settings by checking the SNP->Mode->ReceeiveFilterSettings,

-  SNP->Mode->MCastFilterCount and SNP->Mode->MCastFilter fields.

-

-  Note: Some network drivers and/or devices will automatically promote

-  receive filter settings if the requested setting can not be honored.

-  For example, if a request for four multicast addresses is made and

-  the underlying hardware only supports two multicast addresses the

-  driver might set the promiscuous or promiscuous multicast receive filters

-  instead.  The receiving software is responsible for discarding any extra

-  packets that get through the hardware receive filters.

-

-  If ResetMCastFilter is TRUE, then the multicast receive filter list

-  on the network interface will be reset to the default multicast receive

-  filter list.  If ResetMCastFilter is FALSE, and this network interface

-  allows the multicast receive filter list to be modified, then the

-  MCastFilterCnt and MCastFilter are used to update the current multicast

-  receive filter list.  The modified receive filter list settings can be

-  found in the MCastFilter field of EFI_SIMPLE_NETWORK_MODE.

-

-  This routine calls ::ReceiveFilterUpdate to update the receive

-  state in the network adapter.

-

-  @param [in] pSimpleNetwork    Protocol instance pointer

-  @param [in] Enable            A bit mask of receive filters to enable on the network interface.

-  @param [in] Disable           A bit mask of receive filters to disable on the network interface.

-                                For backward compatibility with EFI 1.1 platforms, the

-                                EFI_SIMPLE_NETWORK_RECEIVE_MULTICAST bit must be set

-                                when the ResetMCastFilter parameter is TRUE.

-  @param [in] bResetMCastFilter Set to TRUE to reset the contents of the multicast receive

-                                filters on the network interface to their default values.

-  @param [in] MCastFilterCnt    Number of multicast HW MAC address in the new MCastFilter list.

-                                This value must be less than or equal to the MaxMCastFilterCnt

-                                field of EFI_SIMPLE_NETWORK_MODE.  This field is optional if

-                                ResetMCastFilter is TRUE.

-  @param [in] pMCastFilter      A pointer to a list of new multicast receive filter HW MAC

-                                addresses.  This list will replace any existing multicast

-                                HW MAC address list.  This field is optional if ResetMCastFilter

-  This function updates the SNP driver status.

-  

-  This function gets the current interrupt and recycled transmit

-  buffer status from the network interface.  The interrupt status

-  and the media status are returned as a bit mask in InterruptStatus.

-  If InterruptStatus is NULL, the interrupt status will not be read.

-  Upon successful return of the media status, the MediaPresent field

-  of EFI_SIMPLE_NETWORK_MODE will be updated to reflect any change

-  of media status.  If TxBuf is not NULL, a recycled transmit buffer

-  address will be retrived.  If a recycled transmit buffer address

-  is returned in TxBuf, then the buffer has been successfully

-  transmitted, and the status for that buffer is cleared.

-

-  This function calls ::Ax88772Rx to update the media status and

-  queue any receive packets.

-

-  @param [in] pSimpleNetwork    Protocol instance pointer

-  @param [in] pInterruptStatus  A pointer to the bit mask of the current active interrupts.

-                                If this is NULL, the interrupt status will not be read from

-                                the device.  If this is not NULL, the interrupt status will

-                                be read from teh device.  When the interrupt status is read,

-                                it will also be cleared.  Clearing the transmit interrupt

-                                does not empty the recycled transmit buffer array.

-  @param [out] ppTxBuf          Recycled transmit buffer address.  The network interface will

-                                not transmit if its internal recycled transmit buffer array is

-                                full.  Reading the transmit buffer does not clear the transmit

-                                interrupt.  If this is NULL, then the transmit buffer status

-                                will not be read.  If there are not transmit buffers to recycle

-                                and TxBuf is not NULL, *TxBuf will be set to NULL.

-/**

-  This function is used to enable and disable the hardware and software receive

-  filters for the underlying network device.

-

-  The receive filter change is broken down into three steps:

-

-    1.  The filter mask bits that are set (ON) in the Enable parameter

-        are added to the current receive filter settings.

-

-    2.  The filter mask bits that are set (ON) in the Disable parameter

-        are subtracted from the updated receive filter settins.

-

-    3.  If the resulting filter settigns is not supported by the hardware

-        a more liberal setting is selected.

-

-  If the same bits are set in the Enable and Disable parameters, then the bits

-  in the Disable parameter takes precedence.

-

-  If the ResetMCastFilter parameter is TRUE, then the multicast address list

-  filter is disabled (irregardless of what other multicast bits are set in

-  the enable and Disable parameters).  The SNP->Mode->MCastFilterCount field

-  is set to zero.  The SNP->Mode->MCastFilter contents are undefined.

-

-  After enableing or disabling receive filter settings, software should

-  verify the new settings by checking the SNP->Mode->ReceeiveFilterSettings,

-  SNP->Mode->MCastFilterCount and SNP->Mode->MCastFilter fields.

-

-  Note: Some network drivers and/or devices will automatically promote

-  receive filter settings if the requested setting can not be honored.

-  For example, if a request for four multicast addresses is made and

-  the underlying hardware only supports two multicast addresses the

-  driver might set the promiscuous or promiscuous multicast receive filters

-  instead.  The receiving software is responsible for discarding any extra

-  packets that get through the hardware receive filters.

-

-  If ResetMCastFilter is TRUE, then the multicast receive filter list

-  on the network interface will be reset to the default multicast receive

-  filter list.  If ResetMCastFilter is FALSE, and this network interface

-  allows the multicast receive filter list to be modified, then the

-  MCastFilterCnt and MCastFilter are used to update the current multicast

-  receive filter list.  The modified receive filter list settings can be

-  found in the MCastFilter field of EFI_SIMPLE_NETWORK_MODE.

-

-  This routine calls ::ReceiveFilterUpdate to update the receive

-  state in the network adapter.

-

-  @param [in] pSimpleNetwork    Protocol instance pointer

-  @param [in] Enable            A bit mask of receive filters to enable on the network interface.

-                                For backward compatibility with EFI 1.1 platforms, the

-                                EFI_SIMPLE_NETWORK_RECEIVE_MULTICAST bit must be set

-                                when the ResetMCastFilter parameter is TRUE.

-  @param [in] bResetMCastFilter Set to TRUE to reset the contents of the multicast receive

-                                filters on the network interface to their default values.

-  @param [in] MCastFilterCnt    Number of multicast HW MAC address in the new MCastFilter list.

-                                This value must be less than or equal to the MaxMCastFilterCnt

-                                field of EFI_SIMPLE_NETWORK_MODE.  This field is optional if

-                                ResetMCastFilter is TRUE.

-  @param [in] pMCastFilter      A pointer to a list of new multicast receive filter HW MAC

-                                addresses.  This list will replace any existing multicast

-                                HW MAC address list.  This field is optional if ResetMCastFilter

-  Cirrus Logic 5430 Controller Driver.

-  This driver is a sample implementation of the UGA Draw and Graphics Output

-  Protocols for the Cirrus Logic 5430 family of PCI video controllers.

-  This driver is only usable in the EFI pre-boot environment.

-  This sample is intended to show how the UGA Draw and Graphics output Protocol

-  is able to function.

-  The UGA I/O Protocol is not implemented in this sample.

-  A fully compliant EFI UGA driver requires both

-  the UGA Draw and the UGA I/O Protocol.  Please refer to Microsoft's

-  documentation on UGA for details on how to write a UGA driver that is able

-  to function both in the EFI pre-boot environment and from the OS runtime.

-# Cirrus Logic 5430 Controller Driver.This driver is a sample implementation

-#  of the UGA Draw Protocol for the Cirrus Logic 5430 family of PCI video controllers.

-#  This driver is only usable in the EFI pre-boot environment. This sample is

-#  intended to show how the UGA Draw Protocol is able to function. The UGA I/O

-#  Protocol is not implemented in this sample. A fully compliant EFI UGA driver

-#  requires both the UGA Draw and the UGA I/O Protocol. Please refer to Microsoft's

-#  documentation on UGA for details on how to write a UGA driver that is able

-#  to function both in the EFI pre-boot environment and from the OS runtime.

-2. Your commit message must include your "Signed-off-by" signature,

-   and "Contributed-under" message.

-3. Your "Contributed-under" message explicitly states that the

-   contribution is made under the terms of the specified

-   contribution agreement.  Your "Contributed-under" message

-   must include the name of contribution agreement and version.

-   For example: Contributed-under: TianoCore Contribution Agreement 1.0

-   The "TianoCore Contribution Agreement" is included below in

-   this document.

-4. Submit your code to the TianoCore project using the process

-   that the project documents on its web page.  If the process is

-   not documented, then submit the code on development email list

-   for the project.

-5. It is preferred that contributions are submitted using the same

-   copyright license as the base project. When that is not possible,

-   then contributions using the following licenses can be accepted:

-  This routine will detect what phy we are using, set the line

-  speed, FDX or HDX, and configure the phy if necessary.

-  The following combinations are supported:

-  - TX or T4 PHY alone at PHY address 1

-  - T4 or TX PHY at address 1 and MII PHY at address 0

-  - 82503 alone (10Base-T mode, no full duplex support)

-  - 82503 and MII PHY (TX or T4) at address 0

-  The sequence / priority of detection is as follows:

-  - PHY 1 with cable termination

-  - PHY 0 with cable termination

-  - PHY 1 (if found) without cable termination

-  - 503 interface

-  Additionally auto-negotiation capable (NWAY) and parallel

-  detection PHYs are supported. The flow-chart is described in

-  the 82557 software writer's manual.

-  NOTE:  1.  All PHY MDI registers are read in polled mode.

-  2.  The routines assume that the 82557 has been RESET and we have

-  obtained the virtual memory address of the CSR.

-  3.  PhyDetect will not RESET the PHY.

-  4.  If FORCEFDX is set, SPEED should also be set. The driver will

-  check the values for inconsistency with the detected PHY

-  technology.

-  5.  PHY 1 (the PHY on the adapter) may have an address in the range

-  1 through 31 inclusive. The driver will accept addresses in

-  this range.

-  6.  Driver ignores FORCEFDX and SPEED overrides if a 503 interface

-  is detected.
