/*
 * Maximum snapshot length.
 *
 * Somewhat arbitrary, but chosen to be:
 *
 *    1) big enough for maximum-size Linux loopback packets (65549)
 *       and some USB packets captured with USBPcap:
 *
 *           http://desowin.org/usbpcap/
 *
 *       (> 131072, < 262144)
 *
 * and
 *
 *    2) small enough not to cause attempts to allocate huge amounts of
 *       memory; some applications might use the snapshot length in a
 *       savefile header to control the size of the buffer they allocate,
 *       so a size of, say, 2^31-1 might not work well.  (libpcap uses it
 *       as a hint, but doesn't start out allocating a buffer bigger than
 *       2 KiB, and grows the buffer as necessary, but not beyond the
 *       per-linktype maximum snapshot length.  Other code might naively
 *       use it; we want to avoid writing a too-large snapshot length,
 *       in order not to cause that code problems.)
 *
 * We don't enforce this in pcap_set_snaplen(), but we use it internally.
