Overview of Networking Drivers
|
|
==============================
|
|
|
|
The networking drivers may be classified in two categories:
|
|
|
|
- physical for real devices
|
|
- virtual for emulated devices
|
|
|
|
Some physical devices may be shaped through a virtual layer as for
|
|
SR-IOV.
|
|
The interface seen in the virtual environment is a VF (Virtual Function).
|
|
|
|
The ethdev layer exposes an API to use the networking functions
|
|
of these devices.
|
|
The bottom half part of ethdev is implemented by the drivers.
|
|
Thus some features may not be implemented.
|
|
|
|
There are more differences between drivers regarding some internal properties,
|
|
portability or even documentation availability.
|
|
Most of these differences are summarized below.
|
|
|
|
More details about features can be found in :doc:`features`.
