Hello Qi,

Many thanks for posting your inquiry on the Mellanox Community.

Based on the information provided in a previous Community Post, this request should be re-directed to SoftROCE community → https://github.com/SoftRoCE/rxe-dev/wiki/rxe-dev:-Home

Also make sure that when you do the test with SOFTRoCE, no OFED is installed.

Additional note: Configuring SoftROCE for RHEL 7 → https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-configuring_soft-_roce

For further information regarding to SoftROCE for your network adapter, please reach out to your vendor in case you are not using Mellanox adapters.

Many thanks,
