- * packet-wlancap.c
- * Decode packets with a AVS-WLAN header
- *
- * AVS linux-wlan-based products use a new sniff header to replace the
- * old prism2-specific one dissected in packet-prism2.c. This one has
- * additional fields, is designed to be non-hardware-specific, and more
- * importantly, version and length fields so it can be extended later
- * without breaking anything.
- *
- * See
- *
- * https://mail.shaftnet.org/chora/browse.php?rt=wlanng&f=trunk%2Fdoc%2Fcapturefrm.txt
