Functions

func LoadTcBpf

func LoadTcBpf() (*ebpf.CollectionSpec, error)

LoadTcBpf returns the embedded CollectionSpec for TcBpf.

func LoadTcBpfObjects

func LoadTcBpfObjects(obj interface{}, opts *ebpf.CollectionOptions) error

LoadTcBpfObjects loads TcBpf and converts it into a struct.

The following types are suitable as obj argument:

*TcBpfObjects
*TcBpfPrograms
*TcBpfMaps

See ebpf.CollectionSpec.LoadAndAssign documentation for details.
