+  Performs read and write operations on the NVRAM device attached to a network

+  interface.

+

+  This function performs read and write operations on the NVRAM device attached

+  to a network interface. If ReadWrite is TRUE, a read operation is performed.

+  If ReadWrite is FALSE, a write operation is performed. Offset specifies the

+  byte offset at which to start either operation. Offset must be a multiple of

+  NvRamAccessSize , and it must have a value between zero and NvRamSize.

+  BufferSize specifies the length of the read or write operation. BufferSize must

+  also be a multiple of NvRamAccessSize, and Offset + BufferSize must not exceed

+  NvRamSize.

+  If any of the above conditions is not met, then EFI_INVALID_PARAMETER will be

+  returned.

+  If all the conditions are met and the operation is "read," the NVRAM device

+  attached to the network interface will be read into Buffer and EFI_SUCCESS

+  will be returned. If this is a write operation, the contents of Buffer will be

+  used to update the contents of the NVRAM device attached to the network

+  interface and EFI_SUCCESS will be returned.

+

+  It does the basic checking on the input parameters and retrieves snp structure

+  and then calls the read_nvdata() call which does the actual reading

+

+  @param This       A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.

+  @param ReadWrite  TRUE for read operations, FALSE for write operations.

+  @param Offset     Byte offset in the NVRAM device at which to start the read or

+                    write operation. This must be a multiple of NvRamAccessSize

+                    and less than NvRamSize. (See EFI_SIMPLE_NETWORK_MODE)

+  @param BufferSize The number of bytes to read or write from the NVRAM device.

+                    This must also be a multiple of NvramAccessSize.

+  @param Buffer     A pointer to the data buffer.

+

+  @retval EFI_SUCCESS           The NVRAM access was performed.

+  @retval EFI_NOT_STARTED       The network interface has not been started.

+  @retval EFI_INVALID_PARAMETER One or more of the following conditions is TRUE:

+                                * The This parameter is NULL

+                                * The This parameter does not point to a valid

+                                  EFI_SIMPLE_NETWORK_PROTOCOL  structure

+                                * The Offset parameter is not a multiple of

+                                  EFI_SIMPLE_NETWORK_MODE.NvRamAccessSize

+                                * The Offset parameter is not less than

+                                  EFI_SIMPLE_NETWORK_MODE.NvRamSize

+                                * The BufferSize parameter is not a multiple of

+                                  EFI_SIMPLE_NETWORK_MODE.NvRamAccessSize

+                                * The Buffer parameter is NULL

+  @retval EFI_DEVICE_ERROR      The command could not be sent to the network

+                                interface.

+  @retval EFI_UNSUPPORTED       This function is not supported by the network
