Set Driver Parameters (Oracle Solaris)

1. Locate the path names and the associated instance numbers in the /etc/path_to_inst file.

   For example, on an Oracle SPARC server, you should see output similar to this:

   # grep i40e /etc/path_to_inst
   "/pci@500/pci@2/pci@0/pci@a/network@0" 1 "i40e"
   "/pci@500/pci@2/pci@0/pci@a/network@0,1" 2 "i40e"

   On an Oracle Solaris x86 server, you should see output similar to this:

   # grep i40e /etc/path_to_inst
   "/pci@0,0/pci8086,3c0a@3,2/pci108e,7b15@0" 0 "i40e"
   "/pci@0,0/pci8086,3c0a@3,2/pci108e,7b15@0,1" 1 "i40e"

   In these preceding examples:

   • The first part within the double quotes specifies the hardware node name in the device tree.

   • The number not enclosed in quotes is the instance number (shown in bold for emphasis).

   • The last part in double quotes is the driver name.

   ---

   Note - To identify a PCIe device unambiguously in the i40e.conf file, use the name, parent name, and unit address for the device. In the example, the name is pci108e,7b15, the parent is /pci@0,0/pci8086,3c0a@3,2, and the unit address is 0. Refer to the pci(4) man page for more information about the PCIe device specification.

   ---

2. Set the parameters for the i40e devices in one of these ways:
   1. Copy the i40e.conf file to the /etc/driver/drv/ and edit the copied file.

      Save the i40e.conf file.

      Reboot the system.

      See Driver Parameters (Oracle Solaris).

      # "/pci@340/pci@1/pci@0/pci@5/ethernet@0" 0 "i40e"
      # "/pci@340/pci@1/pci@0/pci@5/ethernet@0,1" 1 "i40e"
      # 
      #   name = "pciex8086,1589" parent = "/pci@340/pci@1/pci@0/pci@5"
          unit-address = "0" 
      # rx_ring_size = 2048;

   2. Use the dladm command to set a property.

      # dladm show-linkprop -p flowctrl  net5
      LINK     PROPERTY        PERM VALUE        EFFECTIVE    DEFAULT   POSSIBLE
      net5     flowctrl        rw   no           no           no        no,tx,rx,bi,                                                                  pfc,auto 
      flow_control = 3;

      For bidirectional flow control, type:

      # dladm set-linkprop -p flowctrl=bi  net5
