Functions

func GetPciAddressPrefix

func GetPciAddressPrefix(pciAddress string) string

func HandleEnableSriov

func HandleEnableSriov(totalVfs int, fwCurrent, fwNext, attrs *MlxNic) (needReboot, changeWithoutReboot bool)

handleEnableSriov based on totalVfs it decide to disable (totalVfs=0) or enable (totalVfs changed from 0) sriov and need reboot if enableSriov will change

func HandleLinkType

func HandleLinkType(pciPrefix string, fwData, attr *MlxNic,
	mellanoxNicsSpec map[string]sriovnetworkv1.Interface,
	mellanoxNicsStatus map[string]map[string]sriovnetworkv1.InterfaceExt) (bool, error)

handleLinkType based on existing linkType and requested link

func HandleTotalVfs

func HandleTotalVfs(fwCurrent, fwNext, attrs *MlxNic, ifaceSpec sriovnetworkv1.Interface, isDualPort bool, mellanoxNicsSpec map[string]sriovnetworkv1.Interface) (
	totalVfs int, needReboot, changeWithoutReboot bool)

handleTotalVfs return required total VFs or max (required VFs for dual port NIC) and needReboot if totalVfs will change

func HasMellanoxInterfacesInSpec
