Hello. The server is L2 bridge. uname -a: FreeBSD 8.0-STABLE-201005 FreeBSD 8.0-STABLE-201005 #1: Wed Jun 23 12:29:30 UTC 2010 /usr/src/sys/amd64/compile/MYKERNEL amd64 The network adapter is: Intel Gigabit ET Quad Port Server Adapter (Ethernet controller Intel 82257).
Default drivers version in FreeBSD 8.0-STABLE-201005 is Intel(R) PRO/1000 Network Connection version - 1.9.5. We try to set up options below in /boot/loader.conf: if_igb_load="YES" hw.igb.rxd=4096 hw.igb.txd=4096 hw.igb.num_queues=0 hw.igb.enable_aim=1 hw.igb.low_latency=1000 hw.igb.ave_latency=2000 hw.igb.bulk_latency=4000 hw.igb.rx_process_limit=100 hw.igb.fc_setting=0 hw.igb.lro=0 The system boots successfully with drivers 1.9.5. But there are no specified earlier options in sysctl -a | grep igb.0, for example. sysctl -a|grep igb.0: dev.igb.0.%desc: Intel(R) PRO/1000 Network Connection version - 1.9.5 dev.igb.0.%driver: igb dev.igb.0.%location: slot=0 function=0 dev.igb.0.%pnpinfo: vendor=0x8086 device=0x10e8 subvendor=0x8086 subdevice=0xa02b class=0x020000 dev.igb.0.%parent: pci3 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.rx_processing_limit: 100 We try to change drivers version to 1.8.4 from official site. The system boots successfully too and I can see this options in sysctl -a | grep igb.0. But there was some problem: I can explore only some sites through internet browser, for exmaple yandex.ru. Most of the sites I can`t see through the internet browser. But I can "ping" these sites by DNS name, I get DNS query successfully and I can see by tcpdump server replies. Next we have changed the drivers version to 1.7.4. But wih these options the system does not boot. There was an error: GET BUF: dmamap load failure - 12 I try to change hw.igb.rxd and hw.igb.txd in /boot/loader.conf like: 1.hw.igb.rxd=2048 hw.igb.txd=4096; 2.hw.igb.rxd=1024 hw.igb.txd=1024 - the same error. Also the same error with drivers version 1.7.3. But!!! We have another server: L2 bridge too with the same network adapter. uname -a: FreeBSD 7.2-STABLE-200906 FreeBSD 7.2-STABLE-200906 #1: Tue Oct 6 10:26:41 MSD 2009 /usr/src/sys/amd64/compile/MYKERNEL amd64 And we have no such problems like in bridge FreeBSD 8.0. Can anyone help me? Maybe I shouldn`t initialize such options in /loader.conf? Maybe in somewhere else? Thanks fo reply. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
