OS X driver for Intel onboard LAN

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
  • I219V
  • I219LM
  • I219V2
  • I219LM2
  • I219LM3

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.
• Fully optimized for Yosemite and Mavericks (64bit architecture) but should work with Mountain Lion and Lion too, provided you build from source with the 10.8 or 10.7 SDK.
• 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.
