Formerly Intel Ethernet Drivers

Time to update the driver. Can't compile under new kernel branch 4.10. UPDATE. Finally!

Works just as well as you hoped it would. If, at your own risk, you want to support both 1Gb and 10Gb with SFP+ modules that have not been tested with both--and are not advertised to work with both--just make multispeed_fiber always true: --------------------- ixgbe/ixgbe-4.0.3/src/ixgbe_phy.c ---------------------- index 102dd53..a3e5f74 100644 @@ -1451,7 +1451,7 @@ s32 ixgbe_identify_sfp_module_generic(struct ixgbe_hw *hw) hw->phy.sfp_setup_needed = true; /* Determine if the SFP+ PHY is dual speed or not. */ - hw->phy.multispeed_fiber = false; + hw->phy.multispeed_fiber = true; if (((comp_codes_1g & IXGBE_SFF_1GBASESX_CAPABLE) && (comp_codes_10g & IXGBE_SFF_10GBASESR_CAPABLE)) || ((comp_codes_1g & IXGBE_SFF_1GBASELX_CAPABLE) && @@ -1771,7 +1771,7 @@ s32 ixgbe_identify_qsfp_module_generic(struct ixgbe_hw *hw) hw->phy.sfp_setup_needed = true; /* Determine if the QSFP+ PHY is dual speed or not. */ - hw->phy.multispeed_fiber = false; + hw->phy.multispeed_fiber = true; if (((comp_codes_1g & IXGBE_SFF_1GBASESX_CAPABLE) && (comp_codes_10g & IXGBE_SFF_10GBASESR_CAPABLE)) || ((comp_codes_1g & IXGBE_SFF_1GBASELX_CAPABLE) &&

I cannot comment on the driver as I could not get it work on Ubuntu. I thought i'd give it a go, even though I knew it wasn't apart of the supported list. Ubuntu 14.04, 3.13.0-24-generic kernel, Intel Corporation Ethernet Connection I217-V (rev 05). **UPDATE** Booting without the cable plugged in helped!

For older non-current CentOS boot kernel (such as 1 or 2 sub-revisions behind), you're forced to install the full-source CentOS linux kernel into /usr/src/linux. Cannot rely on 'kernel-devel' package then. Certainly, not Intel's fault. but it works very well.

Great stuff.
