Good idea. Nice addition. Some minor comments below.

I think that this should be an rst doc that is included in the index
file for the nics dir. It should be included right after the overview
in the index.


> +.. _pmd_build_and_run:

If this doc is included in the index then it needs a better first section
title. Something like "Compiling and testing a PMD for a NIC".

Then it should have a short introduction like:

    This section demonstrates how to compile and run a Poll Mode Driver
    (PMD) for the available Network Interface Cards in DPDK using TestPMD.

    TestPMD is one of the reference applications distributed with the
    DPDK. Its main purpose is to forward packets between Ethernet
    ports on a network interface and as such is the best way to test
    a PMD.

It would be good to add a link to the TestPMD into docs but it doesn't have a 
target. We should probably add one (it maybe be possible to link to the RST
file but that syntax isn't generally preferred).

This and the next sections should then become second level headings

Also add at the end of this line or after the command:

    This command will also automatically build testpmd.

We recently changed the docs to use "-l" instead of "-c". Can you make
that change here as well.


Thanks,

John
