Some applications may need multiple doorbells to support parallel processing of threads that each operate on a group of resources. The following uapi methods have been implemented in this patch. - BNXT_RE_METHOD_DBR_ALLOC: This will allow the appliation to create extra doorbell regions and use the associated doorbell page index in CREATE_QP and use the associated DB address while ringing the doorbell. - BNXT_RE_METHOD_DBR_FREE: Free the allocated doorbell region. - BNXT_RE_METHOD_GET_DEFAULT_DBR: Return the default doorbell page index and doorbell page address associated with the ucontext.
