Re: [dpdk-dev] ConnectX4 100GbE - Compilation problem

[george.dit@gmail.com]

Hi Adrien,

Thanks for the prompt reply!
You are right, I didn't go via the DPDK route, in the hope that Mellanox
will provide the exact source and configuration.
DPDK 16.07 from dpdk.org works like a charm and my NIC is in PMD mode,
thanks a lot for your guidance!

Best regards,
Georgios
