> 
> When specifying the attributes of a RSS, some fields can be ignored and
> some default values will be used in PMD. For example, there is a default RSS
> key in the PMD and it will be used to create the TIR if nothing is provided by

> 
> The default value cases were missed in the current implementation and it
> would cause some false positives or crashes.
> 
> The comparison function should be adjusted to take all cases into
> consideration when RSS is used for both green and yellow colors.
