sys/linux: describe BPF helper bpf_ringbuf_output
This helper has the prototype:
bpf_ringbuf_output(void *ringbuf, void *data, u64 size, u64 flags)
We need to prepare the second argument (R2) on the stack. We use an
8 bytes data value initialized to some random value on the stack and
pointed to by R2. The third argument therefore needs to be 8 (for 8
bytes).
