2. Features Overview
This section explains the supported features that are listed in the Overview of Networking Drivers.
As a guide to implementers it also shows the structs where the features are defined and the APIs that can be use to get/set the values.
Following tags used for feature details, these are from driver point of view:
[uses]
: Driver uses some kind of input from the application.
[implements]
: Driver implements a functionality.
[provides]
: Driver provides some kind of data to the application. It is possible
to provide data by implementing some function, but “provides” is used
for cases where provided data can’t be represented simply by a function.
[related]
: Related API with that feature.
