The current mbuf scatter gather feature flag is too ambiguous, as it is not clear if input and/or output buffers can be scatter gather mbufs or not. Therefore, three new flags will replace this flag: - RTE_COMP_FF_OOP_SGL_IN_SGL_OUT - RTE_COMP_FF_OOP_SGL_IN_FB_OUT - RTE_COMP_FF_OOP_LB_IN_SGL_OUT Note that out-of-place flat buffers is supported by default and in-place is not supported by the library.

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