To: edk2-devel; +Cc: Jian J Wang, Hao Wu, Ruiyu Ni, Star Zeng, Jiaxin Wu
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1278
This patch is to delete the Tcp4Dxe driver in MdeModulePkg. The driver
will not be maintained and can't co-work with the dual-stack TcpDxe in
NetworkPkg.
People should use below NetworkPkg drivers instead:
NetworkPkg/TcpDxe/TcpDxe.inf
Which is actively maintained with more bug fixes and new feature support.

This patch is to delete the IScsiDxe driver in MdeModulePkg. The driver
will not be maintained and can't co-work with the dual-stack IScsiDxe in
NetworkPkg.
People should use below NetworkPkg drivers instead:
NetworkPkg/IScsiDxe/IScsiDxe.inf
Which is actively maintained with more bug fixes and new feature support.

- Sends a SCSI Request Packet to a SCSI device that is attached to the SCSI channel. This function
- supports both blocking I/O and nonblocking I/O. The blocking I/O functionality is required, and the
- nonblocking I/O functionality is optional.
-
- @param[in] This A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance.
- @param[in] Target The Target is an array of size TARGET_MAX_BYTES and it represents
- the id of the SCSI device to send the SCSI Request Packet. Each
- transport driver may chose to utilize a subset of this size to suit the needs
- of transport target representation. For example, a Fibre Channel driver
- may use only 8 bytes (WWN) to represent an FC target.
- @param[in] Lun The LUN of the SCSI device to send the SCSI Request Packet.
- @param[in, out] Packet A pointer to the SCSI Request Packet to send to the SCSI device
- specified by Target and Lun.
- @param[in] Event If nonblocking I/O is not supported then Event is ignored, and blocking
- I/O is performed. If Event is NULL, then blocking I/O is performed. If
- Event is not NULL and non blocking I/O is supported, then
- nonblocking I/O is performed, and Event will be signaled when the
- SCSI Request Packet completes.
-
- @retval EFI_SUCCESS The SCSI Request Packet was sent by the host. For bi-directional
- commands, InTransferLength bytes were transferred from
- InDataBuffer. For write and bi-directional commands,
- OutTransferLength bytes were transferred by
- OutDataBuffer.
- @retval EFI_BAD_BUFFER_SIZE The SCSI Request Packet was not executed. The number of bytes that
- could be transferred is returned in InTransferLength. For write
- and bi-directional commands, OutTransferLength bytes were
- transferred by OutDataBuffer. Currently not implemeted.
- @retval EFI_NOT_READY The SCSI Request Packet could not be sent because there are too many
- SCSI Request Packets already queued. The caller may retry again later.
- @retval EFI_DEVICE_ERROR A device error occurred while attempting to send the SCSI Request
- Packet.
- @retval EFI_INVALID_PARAMETER Target, Lun, or the contents of ScsiRequestPacket are invalid.
- @retval EFI_UNSUPPORTED The command described by the SCSI Request Packet is not supported
- by the host adapter. This includes the case of Bi-directional SCSI
- commands not supported by the implementation. The SCSI Request
- Packet was not sent, so no additional status information is available.
- Currently not implemeted.
- @retval EFI_TIMEOUT A timeout occurred while waiting for the SCSI Request Packet to execute.

-# This module produces EFI iSCSI Initiator Name Protocol upon EFI TCPv4 Protocol
-# and EFI DHCPv4 Protocol, to provide the capability to do the transport for SCSI
-# data over TCP/IP. It installs EFI HII Configuration Access Protocol to provide
-# one way to configurate the iSCSI setting. This driver only supports IPv4 network
-# stack.
-#
-# Notes:
-# 1) This driver can't co-work with the IScsiDxe driver in NetworkPkg.
-# 2) This driver might have some issues that have been fixed in the IScsiDxe driver
-# in NetworkPkg.
-# 3) This driver supports fewer features than the IScsiDxe driver in NetworkPkg
-# (e.g. IPv6, Dns support for target URL configuration, iSCSI keyword support).
-# 4) IScsiDxe driver in NetworkPkg is recommended for use instead of this one even
-# though both of them can be used.

# The iSCSI driver provides iSCSI service in the preboot environment and supports
# booting over iSCSI. This driver supports both IPv4 and IPv6 network stack.
#
-# Notes:
-# 1) This driver can't co-work with the IScsiDxe driver in MdeModulePkg.
-# 2) This driver includes more bug fixes and supports more features (e.g. IPv6, Dns
-# support for target URL configuration, iSCSI keyword support) than the IscsiDxe
-# driver in MdeModulePkg. So, we recommend using this driver even though both of
-# them can be used.
-# 3) This driver depends on OpenSSL. To use this driver, please follow the
-# instructions found in the file "OpenSSL-HOWTO.txt" located in
-# CryptoPkg\Library\OpensslLib to enable the OpenSSL building first.

This patch is to delete the UefiPxeBcDxe driver in MdeModulePkg. The
driver will not be maintained and can't co-work with the dual-stack
UefiPxeBcDxe in NetworkPkg.
People should use below NetworkPkg drivers instead:
NetworkPkg/UefiPxeBcDxe/UefiPxeBcDxe.inf
Which is actively maintained with more bug fixes and new feature support.

-/**
- Used to perform TFTP and MTFTP services.
-
- This function is used to perform TFTP and MTFTP services. This includes the
- TFTP operations to get the size of a file, read a directory, read a file, and
- write a file. It also includes the MTFTP operations to get the size of a file,
- read a directory, and read a file. The type of operation is specified by Operation.
- If the callback function that is invoked during the TFTP/MTFTP operation does
- not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will
- be returned.
- For read operations, the return data will be placed in the buffer specified by
- BufferPtr. If BufferSize is too small to contain the entire downloaded file,
- then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero
- or the size of the requested file (the size of the requested file is only returned
- if the TFTP server supports TFTP options). If BufferSize is large enough for the
- read operation, then BufferSize will be set to the size of the downloaded file,
- and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp() services
- should use the get-file-size operations to determine the size of the downloaded
- file prior to using the read-file operations-especially when downloading large
- (greater than 64 MB) files-instead of making two calls to the read-file operation.
- Following this recommendation will save time if the file is larger than expected
- and the TFTP server does not support TFTP option extensions. Without TFTP option
- extension support, the client has to download the entire file, counting and discarding
- the received packets, to determine the file size.
- For write operations, the data to be sent is in the buffer specified by BufferPtr.
- BufferSize specifies the number of bytes to send. If the write operation completes
- successfully, then EFI_SUCCESS will be returned.
- For TFTP "get file size" operations, the size of the requested file or directory
- is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server
- does not support options, the file will be downloaded into a bit bucket and the
- length of the downloaded file will be returned. For MTFTP "get file size" operations,
- if the MTFTP server does not support the "get file size" option, EFI_UNSUPPORTED
- will be returned.
- This function can take up to 10 seconds to timeout and return control to the caller.
- If the TFTP sequence does not complete, EFI_TIMEOUT will be returned.
- If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE,
- then the TFTP sequence is stopped and EFI_ABORTED will be returned.
- The format of the data returned from a TFTP read directory operation is a null-terminated
- filename followed by a null-terminated information string, of the form
- "size year-month-day hour:minute:second" (i.e. %d %d-%d-%d %d:%d:%f - note that
- the seconds field can be a decimal number), where the date and time are UTC. For
- an MTFTP read directory command, there is additionally a null-terminated multicast
- IP address preceding the filename of the form %d.%d.%d.%d for IP v4. The final
- entry is itself null-terminated, so that the final information string is terminated

- packets whose reception is enabled in hardware-physical NIC address (unicast),

- UdpRead() does not modify the IP filter settings.
- Dhcp(), Discover(), and Mtftp() set the IP filter, and return with the IP receive
- filter list emptied and the filter set to EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP.
- If an application or driver wishes to preserve the IP receive filter settings,
- it will have to preserve the IP receive filter settings before these calls, and

- requested (for example, PROMISCUOUS with anything else) or if the device does not
- support a requested filter setting and it cannot be accommodated in software
- (for example, PROMISCUOUS not supported), EFI_INVALID_PARAMETER will be returned.
- The IPlist field is used to enable IPs other than the StationIP. They may be
- multicast or unicast. If IPcnt is set as well as EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP,
- then both the StationIP and the IPs from the IPlist will be used.

-## @file
-# This module produces EFI Preboot Execution Environment (PXE) Base Code Protocol.
-#
-# This module produces EFI PXE Base Code Protocol upon EFI MMP Protocl and IPv4
-# network stack, used to control PXE-compatible devices. It produces EFI Load File
-# Protocol to provide one clean way to otain control from the boot manager if the
-# boot patch is from the remote device. This driver only supports IPv4 network stack.
-#
-# Notes:
-# 1) This driver can't co-work with the UefiPxeBcDxe driver in NetworkPkg.
-# 2) This driver might have some issues that have been fixed in the UefiPxeBcDxe
-# driver in NetworkPkg.
-# 3) This driver supports fewer features than the UefiPxeBcDxe driver in NetworkPkg
-# (e.g. IPv6, MTFTP windowsize).
-# 4) UefiPxeBcDxe driver in NetworkPkg is recommended for use instead of this one even
-# though both of them can be used.

> - Used to perform TFTP and MTFTP services.
> -
> - This function is used to perform TFTP and MTFTP services. This includes the
> - TFTP operations to get the size of a file, read a directory, read a file, and
> - write a file. It also includes the MTFTP operations to get the size of a file,
> - read a directory, and read a file. The type of operation is specified by
> Operation.
> - If the callback function that is invoked during the TFTP/MTFTP operation does
> - not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then
> EFI_ABORTED will
> - be returned.
> - For read operations, the return data will be placed in the buffer specified by
> - BufferPtr. If BufferSize is too small to contain the entire downloaded file,
> - then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to
> zero
> - or the size of the requested file (the size of the requested file is only returned
> - if the TFTP server supports TFTP options). If BufferSize is large enough for the
> - read operation, then BufferSize will be set to the size of the downloaded file,
> - and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp()
> services
> - should use the get-file-size operations to determine the size of the
> downloaded
> - file prior to using the read-file operations-especially when downloading large
> - (greater than 64 MB) files-instead of making two calls to the read-file
> operation.
> - Following this recommendation will save time if the file is larger than expected
> - and the TFTP server does not support TFTP option extensions. Without TFTP
> option
> - extension support, the client has to download the entire file, counting and
> discarding
> - the received packets, to determine the file size.
> - For write operations, the data to be sent is in the buffer specified by BufferPtr.
> - BufferSize specifies the number of bytes to send. If the write operation
> completes
> - successfully, then EFI_SUCCESS will be returned.
> - For TFTP "get file size" operations, the size of the requested file or directory
> - is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server
> - does not support options, the file will be downloaded into a bit bucket and the
> - length of the downloaded file will be returned. For MTFTP "get file size"
> operations,
> - if the MTFTP server does not support the "get file size" option,
> EFI_UNSUPPORTED
> - will be returned.
> - This function can take up to 10 seconds to timeout and return control to the
> caller.
> - If the TFTP sequence does not complete, EFI_TIMEOUT will be returned.
> - If the Callback Protocol does not return
> EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE,
> - then the TFTP sequence is stopped and EFI_ABORTED will be returned.
> - The format of the data returned from a TFTP read directory operation is a null-
> terminated
> - filename followed by a null-terminated information string, of the form
> - "size year-month-day hour:minute:second" (i.e. %d %d-%d-%d %d:%d:%f -
> note that
> - the seconds field can be a decimal number), where the date and time are UTC.
> For
> - an MTFTP read directory command, there is additionally a null-terminated
> multicast
> - IP address preceding the filename of the form %d.%d.%d.%d for IP v4. The
> final
> - entry is itself null-terminated, so that the final information string is terminated
> - with two null octets.

# PXE-compatible device for network access or booting. This driver supports
# both IPv4 and IPv6 network stack.
#
-# Notes:
-# 1) This driver can't co-work with the UefiPxeBcDxe driver in MdeModulePkg.
-# 2) This driver includes more bug fixes and supports more features (e.g. IPv6,
-# MTFTP windowsize) than the UefiPxeBcDxe driver in MdeModulePkg. So, we
-# recommend using this driver even though both of them can be used.
