Overview

Package datapath defines the interfaces to abstract all platform specific datapath components.

Current datapath implementations:

pkg/datapath/linux
pkg/datapath/fake

Datapath provides the privileged operations to apply control-plane decision to the kernel.

For integration testing a fake counterpart of this module is defined in pkg/datapath/fake/cells.go.

var NodeAddressingCell = cell.Module(
	"node-addressing",
	"Accessors for looking up local node IP addresses",

	cell.Provide(NewNodeAddressing),
)

NodeAddressingCell provides the [NodeAddressing] interface that provides access to local node addressing information. This will be eventually superceded by Table[NodeAddress].
