I'm working on a Dell R720 server. The NIC daugherboard has 4 ports. Qty 2 ports with X540-AT2 and Qty 2 ports with I350.
Using kernel 2.6.39-100.7.1.el6uek.x86_64 using ixgbe 3.9.15 and igb 3.4.7. The max_vfs parameter is working properly with ixgbe NIC ports, but max_vfs is failing with the igb driver. # cat /etc/modprobe.d/ixgbe.conf options ixgbe max_vfs=32,32 # cat /etc/modprobe.d/igb.conf options igb max_vfs=7,7 # lspci 01:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10 Gigabit X540-AT2 (rev 01) 01:00.1 Ethernet controller: Intel Corporation Ethernet Controller 10 Gigabit X540-AT2 (rev 01) 08:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 08:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) # dmesg Intel(R) Gigabit Ethernet Network Driver - version 3.4.7 Copyright (c) 2007-2011 Intel Corporation. igb 0000:08:00.0: PCI INT D -> GSI 19 (level, low) -> IRQ 19 igb 0000:08:00.0: setting latency timer to 64 igb: 0000:08:00.0: igb_validate_option: max_vfs - SR-IOV VF devices set to 7 igb 0000:08:00.0: Failed to initialize SR-IOV virtualization igb 0000:08:00.0: irq 125 for MSI/MSI-X igb 0000:08:00.0: irq 126 for MSI/MSI-X igb 0000:08:00.0: Intel(R) Gigabit Ethernet Network Connection igb 0000:08:00.0: eth2: (PCIe:5.0GT/s:Width x2 ) igb 0000:08:00.0: eth2: MAC: bc:30:5b:ef:bf:14 igb 0000:08:00.0: eth2: PBA No: G14843-011 igb 0000:08:00.0: LRO is disabled igb 0000:08:00.0: Using MSI-X interrupts. 1 rx queue(s), 1 tx queue(s) igb 0000:08:00.1: PCI INT C -> GSI 18 (level, low) -> IRQ 18 igb 0000:08:00.1: setting latency timer to 64 igb: 0000:08:00.1: igb_validate_option: max_vfs - SR-IOV VF devices set to 7 igb 0000:08:00.1: Failed to initialize SR-IOV virtualization igb 0000:08:00.1: irq 127 for MSI/MSI-X igb 0000:08:00.1: irq 128 for MSI/MSI-X igb 0000:08:00.1: Intel(R) Gigabit Ethernet Network Connection igb 0000:08:00.1: eth3: (PCIe:5.0GT/s:Width x2 ) igb 0000:08:00.1: eth3: MAC: bc:30:5b:ef:bf:15 igb 0000:08:00.1: eth3: PBA No: G14843-011 igb 0000:08:00.1: LRO is disabled igb 0000:08:00.1: Using MSI-X interrupts. 1 rx queue(s), 1 tx queue(s) ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
