-Note, the mbuf scatter gather feature (aka chained mbufs, scatter-gather-lists
-or SGLs) indicate all following combinations are supported unless otherwise called
-out in the Limitations section of each PMD.
+.. Note::
 
-* In place operation, input buffer as multiple segments, same buffer used for output
-* Out of place operation, input buffer as single segment and output as multiple segments
-* Out of place operation, input buffer as multiple segments and output as single segment
-* Out of place operation, input buffer as multiple segments and output as multiple segments
+   - "In Place SGL" feature flag stands for "In place Scatter-gather list",
+     which means that an input buffer can consist of multiple segments,
+     being the operation in-place (input address = output address).
+
+   - "OOP SGL In SGL Out" feature flag stands for
+     "Out-of-place Scatter-gather list Input, Scatter-gather 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.
+
+   - "OOP LB In LB Out" feature flag stands for
+     "Out-of-place Linear Buffers Input, Linear Buffers Output",
+     which means that Out-of-place operation is supported,
+     with linear input and output buffers.
+
+   - "RSA PRIV OP KEY EXP" feature flag means PMD support RSA private key
+     operation (Sign and Decrypt) using exponent key type only.
+
+   - "RSA PRIV OP KEY QT" feature flag means PMD support RSA private key
+     operation (Sign and Decrypt) using quintuple (crt) type key only.
+
+   - "Digest encrypted" feature flag means PMD support hash-cipher cases,
+     where generated digest is appended to and encrypted with the data.
