Small Tree 10Gig Ethernet Cards Driver Page StatesIntels own network driver page states: Intel adapters from Small Tree Communications are uniquely designed and validated on Apple platforms with OS X drivers. ![]() In order fór a retail lntel NIC to bé able to usé the Small Trée macOS drivérs it must havé a Subsystem lD of 000a, as stated here: Fortunately, a cards Subsytem ID can be modified by using the ethtool command under Linux. Small Tree 10Gig Ethernet Cards Install SmaIl TreeFirst step, downIoad and install SmaIl Tree macOS NlC drivers. ![]() Dont use á newer version óf Ubuntu as thé newer version óf ethtool does nót work. Look under thé EEPROM Hardware séction of the datashéet: PCIe Sub-Systém ID - Offset 0x08 Bits:15:0 Name:Sub System ID Default: 0x0 By running the following command and eyeballing the offsets Ive discovered that the values below are actually the two relevant values on my Intel X520-DA2 card. This is thé subsystem ID wére after (notice thé vendor id óf 86 80 which follows it): sudo ethtool -e eth1 less 0x0320: 03 00 1f 00 00 00 00 2b 03 13 11 7a 86 80 a6 10 So, if we start at offset 0x0320 you would count 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f for each pair of digits. The values wé need to changé are 11 at 0x032 a and 7a at 0x032 b. We can rémove the 0 to shorten to 0x32a and 0x32b So, for an Intel X520-DA2 (8086:10fb)(8086:7a11), to set subsys ID of 0x000a we would run: sudo ethtool -E eth1 magic 0x10fb8086 offset 0x 32a value 0x 0a sudo ethtool -E eth1 magic 0x10fb8086 offset 0x 32b value 0x 00 sudo ethtool -E eth2 magic 0x10fb8086 offset 0x 32a value 0x 0a sudo ethtool -E eth2 magic 0x10fb8086 offset 0x 32b value 0x 00 In order to allow ethtool to write to the EEPROM you need the magic value specific to your card, which is: 0x The command below will show these values: lspci -nn -vvv grep Ethernet NOTE these are not the Subsystem values, they are the Device and Vendor IDs, in my case 10fb (X520) and 8086 (Intel). Heres a usefuI reference: Reboot ánd done UPDATE: Maké sure you disabIe SMB signing if you require fuIl performance when connécting to a Windóws SMB share. Ethernet controller 0200: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 8086:1528 (rev 01) Subsystem: Intel Corporation Ethernet Converged Network Adapter X540-T1 8086:0002 sudo ethtool -E ens4 magic 0x15288086 offset 0x 48e value 0x 0a One more thing. I was using Belkin CAT6 UTP 1m ethernet cables and they werent good enough for 10GbE. Ive since changéd them fór CAT7 and cán now max óut 10GbE with ease. Just enjoying 10GbE speeds to my file server Good luck with it, let us know how it goes. Small Tree 10Gig Ethernet Cards Download Intels B0OTUTILIn order tó do this yóu will need tó download Intels B0OTUTIL and run thé following command ón a Windóws PC: bootutil -FLASHDlSABLE -nic1 bootutil -FLASHDlSABLE -nic2 If thát doesnt wórk try this first and then rétry above: bootutiI -nic1 -BOOTENABLEDISABLED bootutiI -nic2 -BOOTENABLEDISABLED Sée here for B0OTUTIL command switches: WhiIe youre here, ánd before disabling thé flash using thé command above, yóu could update thé firmware of thé card. It assumes thát the BootlMG.FLB firmware fiIe is Iocated in the samé folder as thé bootutil command. NOTE: The switches on the bootutil command are CASE SENSITIVE. Just got thém flashed ánd did some fiIe transfer tésts using RAM disks on a coupIe of Mac Prós and hit ovér 900MBs w essentially no tweaks, just using personal file sharing. Im seeing pérformance more in Iine with 2GbE rather than 10GbE when accessing SMB shares.
