GigE cameras - allow IP configuration and GigE-specific parameters configuration
Added a launch file camera_gige.launch, to allow IP address and subnet configuration for GigE cameras. Also, a few parameters specific to GigE cameras can be tuned :
- device link maximum throughput
- Gev SCPS packet size
The new launch file provides default values for these parameters, if you intend to use them, the parameter enable_gige_parameters has to be set to True, otherwise the values will be ignored.
This was tested with a GigE BlackFly S camera only.
Finally, when using several GigE cameras, the IP configuration somehow fails sometimes, and applies to the wrong camera. I couldn't find a way to fix this issue. So, the code as it is should be used to configure the IP while a single camera is connected, and use default parameters to avoid modifying the IP configuration when several cameras are connected.
