      This project is dedicated to the memory of Mausi, the cat I loved more than anybody else.
       

       
      A few days before Christmas I started my latest project, a new driver for recent Intel onboard LAN controllers. My intention was not to replace hnak's AppleIntelE1000e.kext completely but to deliver best performance and stability on recent hardware. That's why I dropped support for a number of older NICs. Currently the driver supports:
       
      5 Series
      82578LM 82578LC 82578DM 82578DC 6 and 7 Series
      82579LM 82579V 8 and 9 Series
      I217LM I217V I218LM I218V I218LM2 I218V2 I218LM3 100 Series (since V2.1.0d0)
      I219LM I219V 200 Series (since V2.3.0d0)
      I219LM I219V 300 Series (since V2.4.0d0)
      I219LM I219V  
      Key Features of the Driver
      Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission. No-copy receive and transmit. Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer. TCP, UDP and IPv4 checksum offload (receive and transmit). Support for TCP/IPv6 and UDP/IPv6 checksum offload. Makes use of the chip's TCP Segmentation Offload (TSO) feature with IPv4 and IPv6 in order to reduce CPU load while sending large amounts of data (disabled due to hardware bugs). Fully optimized for Sierra (64bit architecture) but should work with older 64bit versions of macOS too, provided you build from source with the appropriate SDK for the target OS. Support for Energy Efficient Ethernet (EEE). VLAN support is implemented but untested as I have no need for it. The driver is published under GPLv2.  
      Current Status
      The driver has been tested successfully with I217V, I218V and 82579V under 10.9.5 and above. The attached archive includes source code as well as a prebuilt binary (debug version) for Mavericks and newer versions of macOS.   Known Issues
      There seem to be problems while using VMware with version 1.x.x of the driver. In case you are affected use version 2.0.0 or newer.  
      FAQ
      Could you add support of for...? Well, you are probably asking me to add support for one of the older NICs like the 82571/2/3/4L or 82583 and the answer will be no as I dropped support for these chips intentionally. They are broken and I lost more than 2 weeks trying to make it work on the 82574L without success. I was asked to add support for I210, I211 and I350 but as these chips have a completely different architecture, which isn't supported by the underlying Linux driver, this is impossible, sorry. Does it work with Snow Leopard or 32 bit kernels? No and I have no plans to make a version for 32 bit kernels or anything older than Lion. WoL from S5 doesn't work with this driver but under Windows it's working. Is this a driver bug? No it isn't, the driver is working as it should because OS X doesn't support WoL from S5.  
      Installation
      Goto /S/L/E and delete AppleIntelE1000e.kext. Recreate the kernel cache. Open System Preferences and delete the corresponding network interface, e. g. en0. Reboot. Install the new driver and recreate the kernel cache. I recommend to use Kext Wizard or a similar utility for the installation. Reboot Open System Preferences again, select Network and check if the new network interface has been created automatically or create it manually now. Configure the interface.  
      Help - I'm getting kernel panics!
      Well, before you start complaining about bugs after you upgraded macOS and ask me to publish a driver update, you should first try to resolve the issue on your own by cleaning the system caches.
      As the driver uses macOS's private network driver interface, which is supposed to be used by Apple provided drivers only, you might run into problems after an OS update because the linker may fail to recognize that IONetworking.kext has been updated and that the driver needs to be linked against the new version (Apple provided drivers avoid this problem because they are always updated together with IONetworking.kext). As a result, the linking process produces garbage and the driver may call arbitrary code when trying to call functions from IONetworking.kext. This usually results in unpredicted behavior or a kernel panic. In order to recover from such a situation, you should clean the System Caches forcing the linker to recreate it's caches:
      Delete all the files in /System/Library/Caches and it's subdirectories but leave the directories and the symbolic links intact. This is very important! Reboot. Recreate the kernel cache. Reboot again.  
      Troubleshooting
      Make sure you have followed the installation instructions especially when you have issues with certain domains while the others are working fine. Use the debug version to collect log data when trying to track down problems. The kernel log messages can be retrieved with "grep kernel /var/log/system.log" in Terminal. Starting from Sierra use "log show --predicate "processID == 0" --debug" in order to retrieve kernel logs. Include the log data when asking for support or giving feedback. I'm an engineer, not a clairvoyant. Don't copy and paste large amounts of log data to your post. Create an archive with the log data and attach it to your post. In case you don't want to make your log data publicly accessible, contact me via PM and I will provide you a mail address to send it directly to me.  Check your BIOS settings. You might want to disable Network Boot and the UEFI Network Stack as these can interfere with the driver. Double check that you have removed any AppleIntelE1000e.kext from your system because it could prevent the driver from working properly. Delete the following files: /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist /Library/Preferences/SystemConfiguration/preferences.plist Verify your bootloader configuration, in particular the kernel flags. Avoid using npci=0x2000 or npci=0x3000.  In Terminal run netstat -s in order to display network statistics. Carefully examine the data for any unusual activity like a high number of packets with bad IP header checksums, etc. In case auto-configuration of the link layer connection doesn't work it might be necessary to select the medium manually in System Preferences under Network for the interface. Use Wireshark to create a packet dump in order to collect diagnostic information. Keep in mind that there are many manufacturers of network equipment. Although Ethernet is an IEEE standard, different implementations may show different behavior causing incompatibilities. In case you are having trouble try a different switch or a different cable.

      Register as a developer on Apple's developer website. A free membership is sufficient. Download a copy of Xcode 5.1.1 and install it on your machine. In the project select 10.8 as the "Base SDK" and the "Deployment Target". Call "Archive" from the menu "Product" and save the built driver. Credits
      Thanks to RehabMan and Yung Raj for running tests and pointing me in the right direction while I was trying to fix TSO. Special thanks to Yung Raj for motivating me when I was about to give up.
