Need help to get more information about "nvme_rdma: nvme completion status=0x4007"

[Jie Tang]

Using the standard 4.8.1 nvme-rdma model to do the NVMf testing. Always hit by 0x4007 in the host side for stress testing.
Check the 0x4007 define as: command abort. This command will generate by NVMe SSD on the target side and pass to host.

Anyone encounter similar error during the NVMf stress testing, need your insight about why we have this error, the SSD been confirmed good when this host failed by 0x4007.  Is any exist known bug of Host nvme driver related to this ?

Thanks
