- jump
- Build any BPF statement including conditional jumps.
- jump_
always - Build an unconditional jump instruction.
- load
- Build an instruction to load a 32-bit value from a constant address.
- ret
- Build an instruction to return a 32-bit constant value.
- stmt
- Build a BPF statement with one 32-bit parameter.
- store
- Build an instruction to store a 32-bit value at a constant address.
