Hi, We are using intel NIC cards and IGB driver running in a LINUX box. Even though the hardware throughput of the NIC card is 1 GBPs , we are not able reach even 25% of the limit.
So my question is, what is the way to enable or configure NAPI for IGB driver. As we use Linux, running kernel version 3.10.40, this version of the Linux kernel supports NAPI interfaces.
