samples/bpf: fix bpf tunnel cleanup
test_tunnel_bpf.sh fails to remove the vxlan11 tunnel device, causing the next geneve tunnelling test case fails. In addition, the geneve reserved bit in tcbpf2_kern.c should be zero, according to the RFC. Signed-off-by: William Tu <u9012063@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
