If my server has two identical Intel NICs, could I use both with DPDK and its applications? 2. If both the NIC cards could be used with DPDK, could I use them with separate 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 reinitialising NIC1 when App2 tries to initialise NIC2?

Hi all, Could someone answer the following questions about the usage of multiple NIC interfaces with DPDK? 1. If my server has two identical Intel NICs, could I use both with DPDK and its applications? 2. If both the NIC cards could be used with DPDK, could I use them with separate 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 reinitialising NIC1 when App2 tries to initialise NIC2? From what I?ve seen, DPDK calls the driver init for all the matching devices (vendor id and device id). Thanks, -Sujith
