Functions

func AddInterfaceFilter

func AddInterfaceFilter(v *vnet.Vnet, s string, ok bool)

func Init

func Init(v *vnet.Vnet, cf Config)

func InitInterfaceEthtool

func InitInterfaceEthtool(v *vnet.Vnet)

func ProcessFibEntry

func ProcessFibEntry(msg *xeth.MsgFibentry, v *vnet.Vnet) (err error)

NB: Using these tests you could replace interface-address message and just use fibentry - use this test for interface address routes

if (msg.Id == xeth.RT_TABLE_LOCAL && msg.Type == xeth.RTN_LOCAL) ||
	(msg.Id == xeth.RT_TABLE_MAIN && msg.Type == xeth.RTN_UNICAST) {

func ProcessInterfaceAddr

func ProcessInterfaceAddr(msg *xeth.MsgIfa, action vnet.ActionType, v *vnet.Vnet) (err error)

func ProcessInterfaceInfo

func ProcessInterfaceInfo(msg *xeth.MsgIfinfo, action vnet.ActionType, v *vnet.Vnet) (err error)

func ProcessIpNeighbor

func ProcessIpNeighbor(msg *xeth.MsgNeighUpdate, v *vnet.Vnet) (err error)

func ProcessZeroGw

func ProcessZeroGw(msg *xeth.MsgFibentry, v *vnet.Vnet, ns *net_namespace, isDel, isLocal, isMainUc bool) (err error)

Zero Gw processing covers 2 major sub-cases:

1. Interface-address setting If local table entry and is a known interface of vnet i.e. front-panel then install an interface address
2. Dummy or any other interface that's not a front panel or vlans of a front panel setting If not a known interface of vnet, we assume it's a dummy and install as a punt adjacency (FIXME - need to filter routes through eth0 and others)

func ScopeTranslate

func ScopeTranslate(scope uint8) string

func SetRxInject

func SetRxInject(v *vnet.Vnet, inject_node_name string)
