|
|
The current Wireshark disector does not continue processing a frame, aka
|
|
6LoWPAN processing, if the FCS is incorrect. Furthermore, the FCS length
|
|
in the disector is hard-coded to be 2 bytes. Some PHY implement different
|
|
length FCS. However, Wireshark will ignore the FCS checking if an FCS is
|
|
not provided. This option intentionally excludes the last n bytes of the
|
|
frame where n is the FCS length of the current radio settings.

|
|
config IEEE802154_I8SHARK_XBEE_APPHDR

|
bool "XBee App Header compensation"
|
|
default n
|
|
---help---
|
|
XBee radios use an optional "application header" to support duplicate
|
|
frame detection. Wireshark does not know about this header and it causes
|
|
packets not to be recognized appropriately (6LoWPAN etc.). This option
|
|
blindly chops the first 2 bytes of payload from all incoming frames to
|
|
remove the header. This option can only be used when sniffing XBee-only
|
|
networks, as any frames not containing the application header will have
|
|
2 arbitrary bytes removed from it.
