I have a server with an Intel X520-LR1 Ethernet card, which is a 10GBase-LR card: http://ark.intel.com/Product.aspx?id=41164 The card contains the Intel 82599ES controller: http://ark.intel.com/Product.aspx?id=41282 pciconf -lv shows: ix0@pci0:28:0:0: class=0x020000 card=0x00068086 chip=0x10fb8086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' class = network subclass = ethernet where /sys/dev/ixgbe/ixgbe_type.h has the PCI ID definition: #define IXGBE_DEV_ID_82599_SFP 0x10FB The problem is that this card is shown by ifconfig as a 10GBase-SR card: % ifconfig ix0 ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4> ether 00:1b:21:7c:7b:94 media: Ethernet autoselect (10Gbase-SR <full-duplex>) status: active I believe this is due to the following code in /sys/dev/ixgbe/ixgbe.c line 423, routine ixgbe_attach(): case IXGBE_DEV_ID_82599_SFP: adapter->optics = IFM_10G_SR; I'm looking at version 1.17.2.12.2.1, from 8.2-RC1, but I see this code is the same in version 1.45, from HEAD: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ixgbe/ixgbe.c?rev=1.45;content-type=text/plain I made a 1-line patch to the 8.2-RC1 code, enclosed below, and now have ifconfig showing the expected value: y% ifconfig ix0 ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4> ether 00:1b:21:7c:7b:94 media: Ethernet autoselect (10Gbase-LR <full-duplex>) status: active Steinar Haug, Nethelp consulting, sthaug@nethelp.no ---------------------------------------------------------------------- --- ixgbe.c.orig 2010-12-21 18:09:25.000000000 +0100 +++ ixgbe.c 2011-01-13 14:31:14.000000000 +0100 @@ -421,7 +421,7 @@ adapter->optics = IFM_10G_LR; break; case IXGBE_DEV_ID_82599_SFP: - adapter->optics = IFM_10G_SR; + adapter->optics = IFM_10G_LR; ixgbe_num_segs = IXGBE_82599_SCATTER; break; case IXGBE_DEV_ID_82598_DA_DUAL_PORT :
