There is no tuning at all on our part in the loader's conf. Find below the sysctls: # sysctl -a |grep igb dev.igb.0.%desc: Intel(R) PRO/1000 Network Connection version - 1.7.3 dev.igb.0.%driver: igb dev.igb.0.%location: slot=0 function=0 dev.igb.0.%pnpinfo: vendor=0x8086 device=0x10d6 subvendor=0x8086 subdevice=0x145a class=0x020000 dev.igb.0.%parent: pci14 dev.igb.0.debug: -1 dev.igb.0.stats: -1 dev.igb.0.flow_control: 3 dev.igb.0.enable_aim: 1 dev.igb.0.low_latency: 128 dev.igb.0.ave_latency: 450 dev.igb.0.bulk_latency: 1200 dev.igb.0.rx_processing_limit: 100 dev.igb.1.%desc: Intel(R) PRO/1000 Network Connection version - 1.7.3 dev.igb.1.%driver: igb dev.igb.1.%location: slot=0 function=1 dev.igb.1.%pnpinfo: vendor=0x8086 device=0x10d6 subvendor=0x8086 subdevice=0x145a class=0x020000 dev.igb.1.%parent: pci14 dev.igb.1.debug: -1 dev.igb.1.stats: -1 dev.igb.1.flow_control: 3 dev.igb.1.enable_aim: 1 dev.igb.1.low_latency: 128 dev.igb.1.ave_latency: 450 dev.igb.1.bulk_latency: 1200 dev.igb.1.rx_processing_limit: 100 _______________________________________________ freebsd-pf@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-pf To unsubscribe, send any mail to "freebsd-pf-unsubscr...@freebsd.org"
