Support for Energy Efficient Ethernet (EEE). 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).įully 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 TCP/IPv6 and UDP/IPv6 checksum offload. TCP, UDP and IPv4 checksum offload (receive and transmit). Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer. Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission. That's why I dropped support for a number of older NICs. My intention was not to replace hnak's AppleIntelE1000e.kext completely but to deliver best performance and stability on recent hardware. This project is dedicated to the memory of Mausi, the cat I loved more than anybody else.Ī few days before Christmas I started my latest project, a new driver for recent Intel onboard LAN controllers.
