This is the 2/3 patch of the patch-set described below. The patch-set contains driver for Huawei's 3rd generation HiNIC Ethernet device that will be available in the future. This is an SRIOV device, designed for data centers. Initially, the driver only supports VFs. Following the discussion over RFC01, the code will be submitted in separate smaller patches where until the last patch the driver is non-functional. The RFC02 submission contains overall view of the entire driver but every patch will be posted as a standalone submission.
