MdeModulePkg: Delete IScsiDxe in MdeModulePkg.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1278
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.

-/**
- This function allows the caller to request the current
- configuration for one or more named elements. The resulting
- string is in <ConfigAltResp> format. Any and all alternative
- configuration strings shall also be appended to the end of the
- current configuration string. If they are, they must appear
- after the current configuration. They must contain the same
- routing (GUID, NAME, PATH) as the current configuration string.
- They must have an additional description indicating the type of
- alternative configuration the string represents,
- "ALTCFG=<StringToken>". That <StringToken> (when
- converted from Hex UNICODE to binary) is a reference to a
- string in the associated string pack.
-
- @param[in] This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
- @param[in] Request A null-terminated Unicode string in
- <ConfigRequest> format. Note that this
- includes the routing information as well as
- the configurable name / value pairs. It is
- invalid for this string to be in
- <MultiConfigRequest> format.
- @param[out] Progress On return, points to a character in the
- Request string. Points to the string's null
- terminator if request was successful. Points
- to the most recent "&" before the first
- failing name / value pair (or the beginning
- of the string if the failure is in the first
- name / value pair) if the request was not
- successful.
- @param[out] Results A null-terminated Unicode string in
- <ConfigAltResp> format which has all values
- filled in for the names in the Request string.
- String to be allocated by the called function.
-
- @retval EFI_SUCCESS The Results string is filled with the
- values corresponding to all requested
- names.
- @retval EFI_OUT_OF_RESOURCES Not enough memory to store the
- parts of the results that must be
- stored awaiting possible future
- protocols.
- @retval EFI_INVALID_PARAMETER For example, passing in a NULL
- for the Request parameter
- would result in this type of
- error. In this case, the
- Progress parameter would be
- set to NULL.
- @retval EFI_NOT_FOUND Routing data doesn't match any
- known driver. Progress set to the
- first character in the routing header.
- Note: There is no requirement that the
- driver validate the routing data. It
- must skip the <ConfigHdr> in order to
- process the names.
- @retval EFI_INVALID_PARAMETER Illegal syntax. Progress set
- to most recent & before the
- error or the beginning of the
- string.
- @retval EFI_INVALID_PARAMETER Unknown name. Progress points
- to the & before the name in
- question.Currently not implemented.

- 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.
