  and the driver's name / value pairs are in <BlockConfig>
  format, it may use the ConfigToBlock helper function (above) to
  simplify the job. Currently not implemented.

/**
  This function applies changes in a driver's configuration.
  Input is a Configuration, which has the routing data for this
  driver followed by name / value configuration pairs. The driver
  must apply those pairs to its configurable storage. If the
  driver's configuration is stored in a linear block of data
  and the driver's name / value pairs are in <BlockConfig>
  format, it may use the ConfigToBlock helper function (above) to
  simplify the job. Currently not implemented.

  @param[in]  This                Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
  @param[in]  Configuration       A null-terminated Unicode string in
                                  <ConfigString> format.   
  @param[out] Progress            A pointer to a string filled in with the
                                  offset of the most recent '&' before the
                                  first failing name / value pair (or the

                                  is in the first name / value pair) or

                                  awaiting distribution.

                                  stored awaiting possible future
