extcap: Catch unknown arguments to fix spaces
- If boolflags are being used, an extra space is added to the call of the extcap filter. This leads to the argumentparser of python to exit with an error-code, and the extcap filter will not start. This patch instead catches the unknown arguments and prints them on stdout, as well as running the dissection with the rest of the arguments list. Basically this is a work-around, for a behaviour not yet fixed in extcap, but it stabilizes the usage of the demo Change-Id: I7589292692b0b3c839909fd09d62a4714cbe869e Reviewed-on: https://code.wireshark.org/review/4638 Reviewed-by: Roland Knall <rknall@gmail.com> Reviewed-by: Tomasz Moń <desowin@gmail.com> Reviewed-by: Pascal Quantin <pascal.quantin@gmail.com>
