    Intel igb driver parameters




      Currently, we are using Intel I-350-T2 cards with igb driver version igb-5.0.6 with our RHEL 6.4 - 64 bit boxes. And we have configured our /etc/modprobe.d/igb.conf file as


      options igb InterruptThrottleRate=0,0 LLIPort=8080,3306


      To my understanding, with these given parameters igb driver will be initialized with both

      igb: 0000:01:00.0: igb_check_options: Interrupt Throttling Rate (ints/sec) turned off

      igb: 0000:01:00.0: igb_validate_option: Low Latency Interrupt TCP Port set to 8080

      Would like to know, the correct way of using these parameters and benefits of those parameter when used individually and combined


      Also, like to have the suggestions and comments from the Community for getting the best out of Intel IGB driver parameter for small packet networks


      Thanks / Chithirai Ganesh
