The purpose of this is to inform the RDMA driver the size of the doorbell BAR that the L2 driver has mapped and the portion that is mapped uncacheable. The unchaeable portion is shared with the RoCE driver. Any remaining unmapped doorbell BAR can be used by the RDMA driver for its own purpose. Currently, the entire L2 portion is mapped uncacheable.
