Synopsis

#include <opendmi/entity/hpe/nic-mac.h>

typedef struct dmi_hpe_nic_mac {
    uint16_t segment;
    uint8_t bus;
    uint8_t devfn;
    dmi_binary_t mac_address;
    dmi_hpe_nic_state_t state;
    uint8_t port;
    const char *uefi_device_path;
} dmi_hpe_nic_mac_t;

Description

The dmi_hpe_nic_mac_t structure holds the decoded HP/HPE NIC PCI and MAC information, which describes a network port the firmware boots from over PXE, one per structure.

The structure is returned by dmi_entity_info for the structures decoded by dmi_hpe_nic_mac_spec, of type DMI_TYPE(hpe_nic), declared in <opendmi/module/hpe.h>, once the HPE extension module (dmi_hpe_module) is enabled, which it is for HP and HPE servers. It lives as long as the context it has been decoded in.

Fields

segment

PCI segment group, zero for a single group topology.

bus

PCI bus.

devfn

PCI device and function, (device << 3) | function.

mac_address

MAC address.

state

State of the port, see dmi_hpe_nic_state: disabled if the bus and the device are zero, and not installed if they have all bits set.

port

Number of the port. Set to UINT8_MAX when the structure holds none.

uefi_device_path

UEFI device path of the port.

Standards

Not part of the SMBIOS specification. Defined by HP and HPE for their servers; the layout is the one dmidecode documents.
