Thomas Monjalon f229692d23 doc: highlight pointed column in NIC overview table
Every cells of a driver column are painted in yellow.

The trick is to generate some empty content as a big column
above and below the pointed cell.

The position: relative attribute is used for the highlight position
but it makes the border to disappear.

The overflow: hidden attribute is used to mask the generated content
outside of the table.

The class .wy-nav-content has a background which masks the highlighting.
Setting an opacity lower than 1, creates a new stack context and let
the column highlight to be shown.

The background of odd rows was grey and opaque. It is redefined with
a transparent alpha ratio in order to see highlighting on such rows.

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.
