If my server has two identical Intel NICs, could I use both with DPDK a= nd its applications? 2. If both the NIC cards could be used with DPDK, could I use them with se= parate instances of applications? E.g., NIC1 used by App1 and NIC2 used by= App2. 3. If answer to qn no 2 is yes, does the driver take care to avoid reiniti= alising NIC1 when App2 tries to initialise NIC2? From what I=92ve seen, DP= DK calls the driver init for all the matching devices (vendor id and device= id). Thanks, -Sujith
