We need to define a precise wording, especially for the words
- interface
- resource
- device
- driver
- module
Following are my thoughts:
An interface is a view of a resource through an API (e.g. an ethdev port).
A resource is a well identified hardware (e.g. a PCI device id).
A device is a hardware function (e.g. a networking port).
Note that some PCI NICs have only one PCI device id for several ports
(Chelsio and Mellanox cases). That's why we need to distinguish device
and resource.
A driver is the code handling a device.
I have read the word module in some patch proposals but I don't really know
what it refers to. Is it a group of drivers in the same file/directory?
