Scope
per-stack

Upper limit on number of packet buffers in each Onload stack. Packet buffers require hardware resources which may become a limiting factor if many stacks are each using many packet buffers. This option can be used to limit how much hardware resource and memory a stack uses. This option has an upper limit determined by the max_packets_per_stack onload module option.

Note: When 'scalable packet buffer mode' is not enabled (see EF_PACKET_BUFFER_MODE) the total number of packet buffers possible in aggregate is limited by a hardware resource.
