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
