Re: [dpdk-users] Multi Queue Support With Mellanox 40GbE NIC - MT27500 Family [ConnectX-3]

[Olga Shern <olgas@mellanox.com>]

Hi Suresh, 

RSS configuration is not supported with  ConnectX-3 PMD.
We added this support for ConnectX-4 PMD, available in DPDK 2.2.

Best Regards,
Olga

Subject: [dpdk-dev] Multi Queue Support With Mellanox 40GbE NIC - MT27500 Family [ConnectX-3]

Hi,
   We are planning to use the Multi Queue features of Mellanox NIC by using RSS to distribute packets among the multiple RX queues.  We have Mellanox ConnectX-3 NIC.
Seems there are lot of limitations in using RSS as there is no support for Hash Key and function update with ConnectX-3 series. Is there any patch available for Mellanox to using RSS by required hash update?

Here is the requirement:

1.      Multi Queue Support

2.      Symmetric IP Hash - SRC IP and DST IP


Please guide me if you have any solution available which will help us in using Mellanox NIC with multi queue feature. Thanks in advance.

DPDK Version: 2.1.0 + Additional patches.
