Hi All,

I have a use-case where my slow path application (control path) is to run
on Linux where as my data path is to run as DPDK application. 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
