5.17. Realtek RTL8169 - emllRTL8169

The parameters to the Realtek RTL8169 Link Layer are setup-specific. The function CreateLinkParmsFromCmdLineRTL8169() in EcSelectLinkLayer.cpp demonstrates how to initialize the Link Layer instance.

struct EC_T_LINK_PARMS_RTL8169

Public Members

EC_T_LINK_PARMS linkParms

Common link parameters. Signature must be set to EC_LINK_PARMS_SIGNATURE_RTL8169

EC_T_BOOL bNotUseDmaBuffers

EC_TRUE: copy buffer before processing, EC_FALSE: Use buffers from DMA (default)

EC_T_BOOL bAckErrInIrq

Acknowledge errors in interrupt handler

EC_T_DWORD dwRxBuffers

Receive buffer count. Must be a power of 2, maximum 1024

EC_T_DWORD dwTxBuffers

Transmit buffer count. Must be a power of 2, maximum 1024

EC_T_BOOL bNoPhyAccess

Don’t use MDIO to set up the PHY

5.17.1. RTL8169 usage under Linux

Because the Linux Kernel module de-initializes the PHY on unloading, Linux must be prevented from loading the r8169 module on startup.
