1564454ff2SPablo de Lara
1664454ff2SPablo de Lara   - "Pass-through" feature flag refers to the ability of the PMD
1764454ff2SPablo de Lara     to let input buffers pass-through it, copying the input to the output,
1864454ff2SPablo de Lara     without making any modifications to it (no compression done).

20a6531d58SPablo de Lara   - "OOP SGL In SGL Out" feature flag stands for
21*d629b7b5SJohn McNamara     "Out-of-place Scatter-gather list Input, Scatter-gather list Output",
22a6531d58SPablo de Lara     which means PMD supports different scatter-gather styled input and output buffers
23a6531d58SPablo de Lara     (i.e. both can consists of multiple segments).
24a6531d58SPablo de Lara
25a6531d58SPablo de Lara   - "OOP SGL In LB Out" feature flag stands for
26a6531d58SPablo de Lara     "Out-of-place Scatter-gather list Input, Linear Buffers Output",
27a6531d58SPablo de Lara     which means PMD supports input from scatter-gathered styled buffers, outputting linear buffers
28a6531d58SPablo de Lara     (i.e. single segment).
29a6531d58SPablo de Lara
30a6531d58SPablo de Lara   - "OOP LB In SGL Out" feature flag stands for
31a6531d58SPablo de Lara     "Out-of-place Linear Buffers Input, Scatter-gather list Output",
32a6531d58SPablo de Lara     which means PMD supports input from linear buffer, outputting scatter-gathered styled buffers.
