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.
