The size of bpf_insn is passed to bpf_load_program instead of the number
of elements as it expects, so ip vrf exec fails with:
$ sudo ip link add vrf-blue type vrf table 10
$ sudo ip link set dev vrf-blue up
$ sudo ip/ip vrf exec vrf-blue ls
Failed to load BPF prog: 'Invalid argument'
last insn is not an exit or jmp
processed 0 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0
