b. The following parameters operate on a per port basis and can be set using
the
/platform/sun4u/kernel/drv/nxge.conf
file.
c. In the following example, the ports of all the Sun x8 Express Dual 10 Gigabit
Ethernet Fiber XFP Low Profile Adapter are being set for load balancing Rx
traffic based on IP source address. The default value is F80 indicating Rx
load balancing based on IP 5-tuple. Notice the semi-colon at the end of the
last parameter.
#
# ------- How to set parameters for a particular interface --------
# The example below shows how to locate the device path and set a
# parameter for a particular nxge interface. (Using jumbo support as
# an example)
#
# Use the following command to find out the device paths for nxge,
# more /etc/path_to_inst | grep nxge
#
# For example, if you see,
# "/pci@7c0/pci@0/pci@8/network@0" 0 "nxge"
# "/pci@7c0/pci@0/pci@8/network@0,1" 1 "nxge"
# "/pci@7c0/pci@0/pci@8/network@0,2" 2 "nxge"
# "/pci@7c0/pci@0/pci@8/network@0,3" 3 "nxge"
#
# then you can enable jumbo for ports 0 and 1 and disable jumbo for ports 2
# and 3 as follows,
#
# name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@8/" unit-address
= "0"
# accept_jumbo = 1;
# name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@8/" unit-address
= "0,1"
# accept_jumbo = 1;
# name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@8/" unit-address
= "0,2"
# accept_jumbo = 0;
# name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@8/" unit-address
= "0,3"
# accept_jumbo = 0;
