Fetch a single firmware inventory entry

[riethm]

UpdateService.firmwareInventory stores the endpoint of the firmware inventory. In 6933b3e, the property was changed from exported to unexported, such that now the only way to access the data in the firmware inventory appears to be through this list method:

// FirmwareInventories gets the collection of firmware inventories of this update service
func (updateService *UpdateService) FirmwareInventories() ([]*SoftwareInventory, error) {

This is useful for discovery, but is expensive when you just want to fetch the inventory data for a specific component (e.g., "BMC-Primary").

Is there a way I'm missing to fetch data for a single firmware inventory entry?

Could you explain how you were accessing the firmware inventory before without doing something like being done in the FirmwareInventories() call?

I called GetSoftwareInventory(), passing the client, and a concatenation of the UpdateService.FirmwareInventory endpoint plus the specific entry ID we are interested in, e.g.: /redfish/v1/UpdateService/FirmwareInventory/BMC-Primary

gofish/redfish/softwareinventory.go

Lines 172 to 175 in 71755ec

	// GetSoftwareInventory will get a SoftwareInventory instance from the service.
	func GetSoftwareInventory(c common.Client, uri string) (*SoftwareInventory, error) {
	return common.GetObject[SoftwareInventory](c, uri)
	}

Where would you get the BMC-Primary name to fetch the specific ID? If it's something already known, we could add a GetSoftwareInventoryByName(c common.Client, item string) call. I suppose we could also do a GetSoftwareInventoryOwnerList() or something like that to get the list of names if needed.

I'm really trying to avoid anywhere that we just give the client a raw Redfish URL to have to fetch on their own. But I suppose if that's the cleanest way to do this, I'm not entirely opposed to the idea.
