      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.

      I want to present you updated RealtekR1000 driver. I added support for new chips according to linux's sources.
      Now it supports RTL8168E,F/8111E,F.It works for me and works better then v2.0.6 from realtek.com.tw. Now I have no problems with sleep/wake. With native driver I sometimes lose LAN after wake.With this driver never.

      UPDATE. In this version I applied my own inventions so my driver differs from native.

      I made some changes according to official Realtek driver 8.037, newest for now. I can't say I take it as a whole. No, my driver is cropped and may not work for some chips.
      Anyway it tested for me in Mavericks.
      Change log:
      - adopted for new chips RTL8168GU/8111GU, 8411B, RTL8168EP/8111EP . But not tested
      - autolink to 1000Mb/s
      - some functions for WOL, not tested.
       
      17.12.2013
      More changes from linux sources implemented
       
      20.12.2013
      Implemented WoL as Mieze did.

      Hello.
      I have system unit Dell Vostro 3267 (i5-6400, Skylake). Information in signature.
      In this system block module installed Atheros AR9565 802.11 b/g/n Wireless Network Adapter, which, as I understand it, combines Wi-Fi - Atheros AR9565 and Bluetooth Qualcomm QCA9565.
       
      I managed to get working Wifi with kext from chunnann.

      Bluetooth works only if you first boot into Windows and then reboot into macOS from it. At the same time, you need to install drivers for bluetooth in Windows from the official Dell website, because the original drivers that Windows downloaded and installed itself - did not allow the bluetooth module to work even in Windows.
      In bluetooth settings, the power button was inactive and there was an eternal search for devices (if macOS was loaded immediately after the PC started). Enable button disable I cured just by adding the folder /kexts/Other kext BrcmBluetoothInjector by writing inside it in the Info.the plist file corresponds to the VendorID and ProductID of my bluetooth (which are displayed in the system report). BrcmBluetoothInjector_Mod.kext.zip
       
      I am disappointed that Windows is able to automatically download the firmware to the bluetooth module during the download, and Hackintosh macOS has not yet done such a kext.
       
      In the search for solutions to the problem I came across here are the options for the text:

      https://osxlatitude.com/forums/topic/2925-bluetooth-firmware-uploader/
      And here's a way - to use a virtual machine to the OS from it to download the firmware to the bluetooth module
      https://osxlatitude.com/forums/topic/10127-updated-nov-2017-fix-btfirmwareuploader-in-macos-high-sierra/
      Unfortunately, not one of these options did not help me to ensure that bluetooth worked when "cold" start the PC in macOS.
       
      1.
      I started to read more about kexts. In texte BrcmPatchRAM says that it is possible to add support for their bluetooth module in this kext. I downloaded the drivers for my bluetooth from the official site and extracted from .exe installer driver files themselves (This is easily done using 7-zip in Windows or using Keka in macOS). There were more files .dfu than others. As I found out .dfu files are compiled firmware files that the driver loads into the bluetooth module. In the instructions to BrcmPatchRAM States only .hex firmware files for Broadcom.
      I started looking for information on the Internet and found out that .hex files are the original "text" of the firmware as well .dfu is compiled .hex files.
      I immediately started looking for converters/decompilers/disassemblers from .in dfu .hex, but found only what's out .hex does .dfu file:
      https://github.com/pjsg/hex2dfu
      https://github.com/plietar/dfuse-tool
      https://github.com/kuro68k/ihex2dfu
      https://github.com/vpelletier/python-dfu
      As well as console utilities "dfu-tool" and "dfu-util" in Linux. I found out that dfu-util can be installed in macOS using Homebrew or use this option (it differs in functionality) https://github.com/the-darkvoid/dfu-util-osx
       
      2.
      I also learned that .dfu files are used in macOS /System/Library/Extensions/IOBluetoothFamily.kext/Contents/PlugIns/IOBluetoothUSBDFU.kext/Contents/Resources
      I think we should try to replace all of them on that file that Windows loads the bluetooth module (I think if you try to do so, you need to make several copies of this file and rename it to the original ones .dfu files to be deleted).
       
      3.
      As is the idea is just mine .dfu file rename to file .zhx and add it to the kext OS-X-BrcmPatchRAM (in BrcmFirmwareRepo.kext). But there is a problem - first, I don't know which one .dfu files are downloaded to my bluetooth, maybe even a few, because there are 3 files > 40 KB IN size and a lot of files ~ 2 KB in size.
       
      4.
      In "dfu-tool" and "dfu-util" I saw commands that extract firmware from the device. Maybe it will be possible to boot into Linux and if bluetooth starts working there, then try to extract the firmware from bluetooth with these utilities, and then add this firmware to kexts somehow.
       
      5.
      In the file BTFirmwareUploader.kex/Contents/MacOS/BTFirmwareUploader inside already have a list of firmwares, but they are in .hex format. Maybe there's a way to replace them with the contents .dfu file?
       
      I will continue to describe the ideas and results of the experiments. If you have any ideas or you can help to solve this problem, do not hesitate to write.
