- Increase MSI-X vectors by 5 for RoCE traffic. - Add macro to check roce support on a device. - Add device-specific doorbell and MSI-X vector fields shared with NIC functionality. - Provide RoCE driver registration and deregistration functions. - Add support functions which will be invoked on adapter add/remove and port up/down events. - Traverse through the list of adapters to invoke callback functions.
