Note that:

    1) pcap_get_selectable_fd() isn't present in all versions of libpcap - it
first appeared in one of the 0.8.x releases - so we should probably check for
its availability and, if it's not available, use pcap_fileno().

    2) pcap_get_selectable_fd() can return -1, which means "sorry, the only
file descriptor I have for this capture device doesn't support select()";
unfortunately, the driver for Endace's DAG card doesn't support select(), so
the DAG module in libpcap sets the selectable FD to -1.
