函数名称：bpf_fill_maxinsns13

函数原型：static int bpf_fill_maxinsns13(struct bpf_test *self)

返回类型：int

参数：

类型参数名称
struct bpf_test *self
377  len等于BPF_MAXINSNS
379  i等于0
381  insn等于分配数组内存
382  如果非insn则返回:负ENOMEM
385  以i小于len减3循环insn[i]等于Internal classic blocks for direct assignment (BPF_LDX | 8-bit | BPF_MSH, 0)
388  insn[len - 3]等于Internal classic blocks for direct assignment (BPF_LD | BPF_IMM, 0xabababab)
389  insn[len - 2]等于Internal classic blocks for direct assignment (BPF_ALU | BPF_XOR | BPF_X, 0)
390  insn[len - 1]等于Internal classic blocks for direct assignment (BPF_RET | BPF_A, 0)
392  insns等于insn
393  len等于len
395  返回:0
