The Napatech Software Suite internally maintains a number of properties.

These properties can be queried by applications that wish to obtain information about
the capabilities of the Napatech driver and installed adapters.

Properties are addressed in a hierarchical fashion. For example: Adapter0.FpgaGeneration
addresses the FpgaGeneration property on adapter 0.

It is also possible to query ini-file settings through the properties interface. These
settings are located under the ini "section". If, for example, an application
wishes to read the "HostBufferHandlerAffinity" setting on adapter 2 the following address
should be used: ini.Adapter2.HostBufferHandlerAffinity

Note: An adapter property's existence does not depend on the adapter type.
All adapters have the same properties regardless of adapter and FPGA generation, but the values of the properties depend on whether the adapter supports the given capabilities.

System properties
Properties in the system section are system wide.

Adapter properties
The adapter section contains properties that are specific to a particular adapter.

See below for a description of the available properties.
