Chapter 4 Configuring e1000g Driver Parameters 45
#
NumTxDescriptors = 256;
# It can have Minimum 80 or Maximum 256 descriptors.
# If it is set to 256 then on Solaris 7.0 you may get
# into problems while trying to load more than 1 nic as
# it will demand lots of memory...
NumRxDescriptors = 256;
# It can have Minimum 80 or Maximum 256 descriptors.
# If it is set to 256 then on Solaris 7.0 you may get
# into problems while trying to load more than 1 nic as
# it will demand lots of memory...
FlowControl = 3;
# 0: Flow control is completely disabled
# 1: Rx flow control is enabled (we can receive pause frames
# but not send pause frames).
# 2: Tx flow control is enabled (we can send pause frames
# but we do not receiving pause frames).
# 3: Both Rx and TX flow control (symmetric) is enabled.
# 4: No software override. The flow control configuration
# in the EEPROM is used.
MaxNumReceivePackets = 32;
# Minimum value can be 16 and Maximum value would be 1024.
# It will be the value for Maximum number of receive packets
# handled per interrupt. More value means more time to process
# interrupts.
MaxFrags = 8;
# Minimum Value would be 2 and Maximum Value would be 8.
TxInterruptDelay = 300;
# In units of 1.024 micro seconds units.
# 2 bytes are allocated for it so maximum value can be 65535.
# 0 is invalid value on the hardware so software will simply
# disable the transmit interrupt delay settings.
MaxFreeListBuf=256;
# Minimum value would be 64 and maximum value would be 4096.
# Adjust it as per memory available as driver may not load if
# there is not enough memory.
MWIEnable = 1;
# Boolean value 0 disables Memory write and invalidate and 1 enables it
# Only PCI 450NX chipset needs this value set to 0.
DmaFairness = 1;
# Boolean value 1 means DMA is fair and 0 means Receive will get priority.
MasterLatencyTimer = 0;
# BIOS normally decides this value for PCI , which is normally 64.
# 0 is a good value to start. Maximum value is 255.
ForceSpeedDuplex=7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7;
# This will force Speed and Duplex for following settings for a typical
instance.
# 1 will set the 10 Mbps speed and Half Duplex mode.
# 2 will set the 10 Mbps speed and Full Duplex mode.
