LucyRTL8125Ethernet 1.1.0

LucyRTL8125Ethernet​

A macOS driver for Realtek RTL8125 2.5GBit Ethernet Controllers

Changelog v1.1.0​

• Updated Linux sources to 9.005.01.
• Fixed auto-negotiation for all speeds (including 2.5 Gigabit).
• Added support for an adaptive poll interval in 2.5 Gigabit mode.

Key Features of the Driver​

• Supports all versions of Realtek's RTL8125 2.5GBit Ethernet Controllers found on recent boards.
• 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).
• TCP segmentation offload over IPv4 and IPv6.
• Support for TCP/IPv4, UDP/IPv4, TCP/IPv6 and UDP/IPv6 checksum offload.
• Supports jumbo frames up to 9000 bytes (strongly recommended for 2.5GBit operation).
• Fully optimized for Catalina. Note that older versions of macOS might not support 2.5GB Ethernet.
• Supports Wake on LAN (untested).
• Supports VLAN (untested).
• Support for Energy Efficient Ethernet (EEE) which can be disabled by setting enableEEE to NO in the drivers Info.plist without rebuild. The default is YES.
• The driver is published under GPLv2.
