    - "Pass-through" feature flag refers to the ability of the PMD
      to let input buffers pass-through it, copying the input to the output,
      without making any modifications to it (no compression done).

+   - "OOP SGL In SGL Out" feature flag stands for
+     "Out-of-place Scatter-gather list Input, Scatter-gater list Output",
+     which means PMD supports different scatter-gather styled input and output buffers
+     (i.e. both can consists of multiple segments).

+   - "OOP SGL In LB Out" feature flag stands for
+     "Out-of-place Scatter-gather list Input, Linear Buffers Output",
+     which means PMD supports input from scatter-gathered styled buffers, outputting linear buffers
+     (i.e. single segment).
