Functions

func CanUseWinKernelProxier 

func CanUseWinKernelProxier(kcompat KernelCompatTester) (bool, error)

CanUseWinKernelProxier returns true if we should use the Kernel Proxier instead of the "classic" userspace Proxier. This is determined by checking the windows kernel version and for the existence of kernel features.

func CleanupLeftovers 

func CleanupLeftovers() (encounteredError bool)

CleanupLeftovers removes all hns rules created by the Proxier It returns true if an error was encountered. Errors are logged.

func Enum 

func Enum(p v1.Protocol) uint16

type Proxier 

type Proxier struct {

	// TODO(imroc): implement node handler for winkernel proxier.
