[dpdk-dev] NIC speed capabilities

[Thomas Monjalon]

Hi drivers maintainers,

The first line of the table in doc/guides/nics/overview.rst is
outstandingly empty!
Since the commit http://dpdk.org/commit/e274f57, it is possible
to announce the speed capabilities of each port.
The first implementation was only trying to fill some realistic values
at the driver level.

Please complete this work to have the exact values depending of the
device model.

Thank you
