CHAPTER 3
Configuring Driver Parameters
This chapter describes how to configure the vca device driver parameters used by
boththe Sun Crypto Accelerator 4000 UTP and MMF Ethernet adapters. Thischapter
contains the following sections:
■“Sun Crypto Accelerator 4000 Ethernet Device Driver (vca) Parameters” on
page23
■“Setting vca Driver Parameters” on page 33
■“Enabling Autonegotiation or Forced Mode for Link Parameters Withthe
OpenBoot PROM” on page 41
■“Sun Crypto Accelerator 4000 Cryptographic and Ethernet Driver Operating
Statistics” on page 43
■“Network Configuration” on page52

Sun Crypto Accelerator 4000 Ethernet

Device Driver (vca) Parameters

The vca device driver controls the Sun Crypto Accelerator 4000 UTP and MMF
Ethernet devices. The vca driver is attached to the UNIX pci name property
pci108e,3de8 for the Sun Crypto Accelerator 4000 (108e is the vendor ID and
3de8 is the PCI device ID).
Youcan manually configure the vca device driver parameters to customize each Sun
Crypto Accelerator 4000 device in your system. This section providesan overview of
the capabilities of the Sun Crypto Accelerator 4000 Ethernet device used in the
board, lists the available vca device driver parameters, and describes how to
configure these parameters.
The Sun Crypto Accelerator 4000 Ethernet UTP and MMF PCI adapters are capable
of the operating speeds and modes listed in “Setting Autonegotiation or Forced
Mode” on page36. By default, the vca device operates in autonegotiation mode
