The server is having with 4 NIC cards out of which 2 cards get binded to numa node 0 and other 2 cards get binded to numa node 2 (as per the /sys/pci/.../numa_node for each card) How to evenly distribute the cards to all the numa nodes so that one card each gets binded to one numa node? Can we control the binding from dpdk, either pmd_ixgbe or igb_uio? -- Regards Rajesh R
