## Members

- pci\_sbdf

  PCI Express Routing ID for the HFI Transport Function.

- mac\_addr

  MAC Address: The MAC address of this HFI, in EUI-48TM format.

- vlan

  The VLAN identifier if the VLAN is associated with this HFI, as defined in IEEE 802.1q-2018 or zeroes if no VLAN is associated with this HFI.

- ip\_origin

  The source of Ethernet L3 configuration information used by the driver or 0 if not used.

- ipaddr

  The IPv4 or IPv6 address of this HFI.

- subnet\_mask\_prefix

  The IPv4 or IPv6 subnet mask in CIDR routing prefix notation.

- gateway\_ipaddr

  The IPv4 or IPv6 address of the IP gateway for this HFI or zeroes if no IP gateway is specified.

- route\_metric

  The cost value for the route indicated by this HFI.

- primary\_dns\_ipaddr

  The IPv4 or IPv6 address of the Primary DNS server for this HFI.

- secondary\_dns\_ipaddr

  The IPv4 or IPv6 address of the Secondary DNS server for this HFI.

- dhcp\_server\_ipaddr

  The IPv4 or IPv6 address of the DHCP server used to assign this HFI address.

- host\_name

  The Host Name string.

- this\_hfi\_is\_default\_route

  If True, then the BIOS utilized this interface described by HFI to be the default route with highest priority. If False, then routes are local to their own scope.

- dhcp\_override

  If True, then HFI information was populated by consuming the DHCP on this interface. If False, then the HFI information was set administratively by a configuration interface to the driver and pre-OS envrionment.
