Hi All,

What are the various means available (as of now) to share a NIC port
between Linux and DPDK applications? Idea is to separate control packets
and data packets; using Linux userspace application to process control
packets while DPDK application to access/process data packets (same NIC
port is carrying both of these packet traffics; control as well as data).

Note: Bifurcated driver is next step but it's not available as of now.


Thanks,
Deepak
