[dpdk-dev] Testpmd with Mellanox ConnectX-3

Hi folks,

Hopefully this is the right place to ask questions. I'm  trying to run
testpmd (and then develop my own applications) with DPDK 1.8 and the
Mellanox ConnectX-3. The setup script/quickstart/Getting Started guide
don't have too much information about what to do if you have a
Mellanox. I've installed libibverbs and libmlx4 system-wide. This is the
closest I found to a guide for the Mellanox:
https://dpdk.readthedocs.org/en/stable/prog_guide/mlx4_poll_mode_drv.html .
When I run testpmd as described by this article, I get "Cause: No probed
ethernet device".

Here are my questions:
1. Is this how I should set the PMD flag for DPDK? "make install T=<arch>
CONFIG_RTE_LIBRTE_MLX4_PMD=y"
2. If not, how should I do it?
3. Does using the Mellanox mean that I shouldn't use igb_uio at all?
4. Do I need to bind the Mellanox to mlx4_core before using testpmd?

I would be happy to contribute to the help page with end-to-end
instructions for using the Mellanox with testpmd.

Best,
Raghav Sethi
