[PATCH OLK-5.10] RDMA/hns: Support query FW cap bit 

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/IAL7SX



----------------------------------------------------------------------

The driver does not know which functions are supported by the FW,
which may cause compatibility problems. When the new driver matches
the old firmware, the firmware returns a success message for
unsupported commands, which may cause misunderstanding.
