Hi, Jason
   I could not express clearly. We hope that the only copy of libhns will be used for the diff
erent type chip(hip06, hip07, ...), and it can distinguish the hardware of these chip at the same time.
Hence, i think that your plan will not attain our demand.

We hope that the only one userspace library file named libhns-rdmav2.so will be used for the different hardware version(hip06, hip07, ...),
because there are only little change between their userspace drivers. So we need to distinguish hardware version.

We can't distinguish them if only matching driver name "hns_roce".
