Subject: Re: [dpdk-dev] [PATCH 0/2] Native uio-based PMD for Mellanox
ConnectX-3 devices
Hello!
Sorry for off topic. But this
uio-based PMD for Mellanox
ConnectX-3 devices
We found that optimizing fragmentation configuration of mlx4 driver performs as
fast as native PMD.
I think we have to re-consider using native driver rather than ib driver.

Answer 1. UIO based driver is faster then ib based driver.
It can saturate 40G link with MTU sized packets using a single thread while
ib wrapper cannot.
Answer 2. Sorry, I missed that. I'll make a new patch email with my real
name.
Question 1. Is it OK if I separate GPL-based and BSD-based code
This is a native UIO-based PMD for Mellanox ConnectX-3 devices.
It uses a persistent memory library in order to provide a persistent
scartch area for the mlx4 HCA driver.
We release the driver itself under BSD license, but to use it for
commercial products, you may have to re-implement the separat

OK, interesting. Do you have numbers and details about your testbed/scenario?

What is the benefit of this UIO approach compared to the OFED based driver?
