Types

type MacLookup

type MacLookup struct {
	sync.Mutex
	// contains filtered or unexported fields
}

MacLookup : lookup network interface by its (permanent) MAC address. Information about network interfaces is cached. Call RefreshCache() to flush and reload the cache content.

func (*MacLookup) GetInterfaceByIndex

func (m *MacLookup) GetInterfaceByIndex(ifIndex int) (netIf NetIf, found bool)

GetInterfaceByIndex : get network interface by its index (Linux kernel interface handle).

func (*MacLookup) GetInterfaceByMAC

func (m *MacLookup) GetInterfaceByMAC(mac net.HardwareAddr, prefix bool) (
	netIf NetIf, found bool)

GetInterfaceByMAC : lookup network interface by its MAC address.

func (*MacLookup) RefreshCache

func (m *MacLookup) RefreshCache()

RefreshCache should be called initially and when the cached data are suspected to be stale.

type NetIf

type NetIf struct {
	IfIndex int
	IfName  string
	MAC     net.HardwareAddr
}

NetIf : network interface.
