Integration with kernel bypass mechanism DPDK

On embedded platforms, moving to DPDK based forwarding enables high data rates for ethernet to ethernet. Currently trying hybrid approach by using MBIM driver as is. Thought of checking any native poll mode support on MBIM driver. Also on WWAN with 5G, some modems claim theoretical data rates close to 5.5Gbps.

Is there a specific reason this is desirable?  Maybe the hardware
you're using is unable to handle high data rates through the WWAN
device using normal interrupt-based schemes?
