Because both control and data packets are going to be received via same NIC card, how will these two flows be separated and passed on to Linux control app and DPDK data path app respectively? In short I want to understand how NIC received packets are separated between Linux Eth driver and PMD (poll mode driver) of DPDK? Thanks for the help in advance. Thanks, Deepak
