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
beginn ing of the string if the failure
is in the first name / value pair) or
the terminating NULL if all was
successful.
@retval EFI_SUCCESS The results have been distributed or are
awaiting distribution.
@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_PARAMETERS Passing in a NULL for the
Results parameter would result
in this type of error.
