Hi all. :-) Please pardon my ignorance as this is a new area for me. I've been googling around for quite some time, but have come up short on answers.
It seems that my igb driver on Centos 5.3 doesn't allow me to set the InterruptThrottleRate. Which surprises me as I've seen plenty of posts in the archives here instructing folks to modify their modprobe.conf ala (options igb InterruptThrottleRate=0,0,0,0). This has worked for me in the past with the e1000 driver. Here's where I'm flummoxed... the fact the modinfo reports no parameters for the igb driver: [r...@nyp1 ~]# cat /etc/redhat-release CentOS release 5.3 (Final) [r...@nyp1 ~]# uname -r 2.6.18-128.el5 [r...@nyp1 ~]# modinfo igb filename: /lib/modules/2.6.18-128.el5/kernel/drivers/net/igb/igb.ko version: 1.2.45-k2 license: GPL description: Intel(R) Gigabit Ethernet Network Driver author: Intel Corporation, <e1000-devel@lists.sourceforge.net> srcversion: EF76B70E5959D571E4D031E alias: pci:v00008086d000010D6sv*sd*bc*sc*i* alias: pci:v00008086d000010A9sv*sd*bc*sc*i* alias: pci:v00008086d000010A7sv*sd*bc*sc*i* alias: pci:v00008086d000010E8sv*sd*bc*sc*i* alias: pci:v00008086d000010E7sv*sd*bc*sc*i* alias: pci:v00008086d000010E6sv*sd*bc*sc*i* alias: pci:v00008086d000010C9sv*sd*bc*sc*i* depends: vermagic: 2.6.18-128.el5 SMP mod_unload gcc-4.1 module_sig: 883f350497747cd75ed35fe9471dce1124ad90a0c4b9f92306ea7e4ca7e8ccc6679774dfd671a60a0bb1e6d878a7ef775dbf516b86814d6cbe69b73e [r...@nyp1 ~]# modinfo e1000 filename: /lib/modules/2.6.18-128.el5/kernel/drivers/net/e1000/e1000.ko version: 7.3.20-k2-NAPI license: GPL description: Intel(R) PRO/1000 Network Driver author: Intel Corporation, <linux.n...@intel.com> srcversion: 61E17F062F789856DE3DC58 alias: pci:v00008086d000010B5sv*sd*bc*sc*i* alias: pci:v00008086d00001099sv*sd*bc*sc*i* alias: pci:v00008086d0000108Asv*sd*bc*sc*i* alias: pci:v00008086d0000107Csv*sd*bc*sc*i* alias: pci:v00008086d0000107Bsv*sd*bc*sc*i* alias: pci:v00008086d0000107Asv*sd*bc*sc*i* alias: pci:v00008086d00001079sv*sd*bc*sc*i* alias: pci:v00008086d00001078sv*sd*bc*sc*i* alias: pci:v00008086d00001077sv*sd*bc*sc*i* alias: pci:v00008086d00001076sv*sd*bc*sc*i* alias: pci:v00008086d00001075sv*sd*bc*sc*i* alias: pci:v00008086d00001028sv*sd*bc*sc*i* alias: pci:v00008086d00001027sv*sd*bc*sc*i* alias: pci:v00008086d00001026sv*sd*bc*sc*i* alias: pci:v00008086d0000101Esv*sd*bc*sc*i* alias: pci:v00008086d0000101Dsv*sd*bc*sc*i* alias: pci:v00008086d0000101Asv*sd*bc*sc*i* alias: pci:v00008086d00001019sv*sd*bc*sc*i* alias: pci:v00008086d00001018sv*sd*bc*sc*i* alias: pci:v00008086d00001017sv*sd*bc*sc*i* alias: pci:v00008086d00001016sv*sd*bc*sc*i* alias: pci:v00008086d00001015sv*sd*bc*sc*i* alias: pci:v00008086d00001014sv*sd*bc*sc*i* alias: pci:v00008086d00001013sv*sd*bc*sc*i* alias: pci:v00008086d00001012sv*sd*bc*sc*i* alias: pci:v00008086d00001011sv*sd*bc*sc*i* alias: pci:v00008086d00001010sv*sd*bc*sc*i* alias: pci:v00008086d0000100Fsv*sd*bc*sc*i* alias: pci:v00008086d0000100Esv*sd*bc*sc*i* alias: pci:v00008086d0000100Dsv*sd*bc*sc*i* alias: pci:v00008086d0000100Csv*sd*bc*sc*i* alias: pci:v00008086d00001009sv*sd*bc*sc*i* alias: pci:v00008086d00001008sv*sd*bc*sc*i* alias: pci:v00008086d00001004sv*sd*bc*sc*i* alias: pci:v00008086d00001001sv*sd*bc*sc*i* alias: pci:v00008086d00001000sv*sd*bc*sc*i* depends: vermagic: 2.6.18-128.el5 SMP mod_unload gcc-4.1 parm: TxDescriptors:Number of transmit descriptors (array of int) parm: TxDescPower:Binary exponential size (2^X) of each transmit descriptor (array of int) parm: RxDescriptors:Number of receive descriptors (array of int) parm: Speed:Speed setting (array of int) parm: Duplex:Duplex setting (array of int) parm: AutoNeg:Advertised auto-negotiation setting (array of int) parm: FlowControl:Flow Control setting (array of int) parm: XsumRX:Disable or enable Receive Checksum offload (array of int) parm: TxIntDelay:Transmit Interrupt Delay (array of int) parm: TxAbsIntDelay:Transmit Absolute Interrupt Delay (array of int) parm: RxIntDelay:Receive Interrupt Delay (array of int) parm: RxAbsIntDelay:Receive Absolute Interrupt Delay (array of int) parm: InterruptThrottleRate:Interrupt Throttling Rate (array of int) parm: SmartPowerDownEnable:Enable PHY smart power down (array of int) parm: KumeranLockLoss:Enable Kumeran lock loss workaround (array of int) parm: copybreak:Maximum size of packet that is copied to a new buffer on receive (uint) parm: debug:Debug level (0=none,...,16=all) (int) module_sig: 883f350497747d075ed35fe9471dce11225710a0bb93a252443ce66126b89eb4ceb8deb6f8a7cea0a0a17b3a4a50de764336ae73a3d12862a2151abbd [r...@nyp1 ~]# /sbin/lspci -v | grep 8257 01:00.0 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) 01:00.1 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) 07:00.0 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) 07:00.1 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) [r...@nyp1 ~]# Note that the PCI device ID is 10:A7 I *greatly* appreciate (read: free beers/pizza when in the Kansas City area <grin/>) any pointers in the right direction.
