...But it's *not* released immediately.  It can be released at any time
(it will probably happen when you call pcap_close, but that's not part
of the API contract either).

The same buffer can be reused and returned later; that's why you keep
getting the same pointer value, and it's also why the buffer is only
valid until the next call to pcap_next_ex (according to the docs).
