The multi-CPU distribution functionality can be configured to place data in 1 – 128 different host buffers with dynamic segment
size, and in 1 – 64 different host buffers with
static segment size. The algorithm used by the SmartNIC for
placing a captured frame in a host buffer is based on flow information (see Ports, Flows, Host Buffers and Streams) as shown in
this figure.

If the specified hash key cannot be calculated for a frame, the frame is distributed using
hash key type 31, round-robin.
