Sun Microsystems 10GBE XFP manual Configuring the nxge Device Driver Parameters

#

#------- Receive DMA Configuration ----------------------------

#

#rxdma-intr-time

#Interrupts after this number of NIU hardware ticks have

#elapsed since the last packet was received.

#A value of zero means no time blanking (Default = 8).

#rxdma-intr-pkts

#Interrupt after this number of packets have arrived since

#the last packet was serviced. A value of zero indicates

#no packet blanking (Default = 20).

#

#Default Interrupt Blanking parameters.

#rxdma-intr-time = 8;

#rxdma-intr-pkts = 20;

#

#

#------- Classification and Load Distribution Configuration ------

#

#class-opt-****-***

#These variables define how each IP class is configured.

#Configuration options range from whether TCAM lookup ie

#is enabled to flow hash generation.

#This parameters also control how the flow template is

#constructed and how packet is distributed within RDC

#groups.

#

#supported classes:

#class-opt-ipv4-tcp class-opt-ipv4-udp class-opt-ipv4-sctp

#class-opt-ipv4-ah class-opt-ipv6-tcp class-opt-ipv6-udp

#class-opt-ipv6-sctp class-opt-ipv6-ah

#

#Configuration bits (The following bits will be decoded

#by the driver as hex format).

#

#0010:use MAC Port (for flow key)

#0020:use L2DA (for flow key)

#0040:use VLAN (for flow key)

#0080:use proto (for flow key)

#0100:use IP src addr (for flow key)

#0200:use IP dest addr (for flow key)

#0400:use Src Port (for flow key)

#0800:use Dest Port (for flow key)

#

#class-opt-ipv4-tcp = fe0;
