limited by PCIe bandwidth when scheduling/assigning hairpin-badwidth between VFs. Changes to E810 HW design introduced scheduler limitation, so that available hairpin-bandwidth is bound to external port speed. In order to address this limitation and enable NFV services such as "service chaining" a knob to adjust the scheduler config was created. Driver can send a configuration message to the FW over admin queue and internal FW logic will reconfigure HW to prioritize and add more BW to VF to VF traffic. As end result for example 10G port will no longer limit hairpin-badwith to 10G and much higher speeds can be achieved.
