Hello Hongbin,

Thank you for posting your inquiry on the NVIDIA Networking Community.

Based on the information provided, you are trying to install MLNX_OFED 4.7-3.2.9.0 on kernel version 5.4. The highest supported kernel version for this driver version is kernel version 5.3.

We recommend to use MLNX_OFED version 4.9-3.1.5.0, which will support your kernel version and the verbs_exp functions as this is the LTS version for Experimental Verbs.

Thank you and regards,

~NVIDIA Networking Technical Support
