How to solve the problem that ”Buffers commands are not supported on your system“

Hello, I met a problem when I use the tool mlnx_qos to set receive buffer size for Mellanox MCX516A-CCAT ConnectX-5 EN NIC. As picture 1 shows, pic1when I input the command then it outputs an error message: “Buffers commands are not supported on your system”.

How can I solve this problem?

The version of OFED is MLNX_OFED_LINUX-5.1-2.3.7.1. The system information is as follows:

Hi Chen

buffer size must be larger than the xoff_threshold.

Example: 87296,87296,0,87296,0,0,0,0 sets receive

buffer size for buffer 0,1,2,3,4,5,6,7 respectively

Please check the xoff_thread

Thanks​
