RDMA/bnxt_re: expose detailed stats retrieved from HW
Broadcom's adapter supports more granular statistics to allow better understanding about the state of the chip when data traffic is flowing. Exposing the detailed stats to the consumer through the standard hook available in the kverbs interface. In order to retrieve all the information, driver implements a firmware command.
