This pull request is targeting net-next and rdma-next branches. These patches have been reviewed by netdev and rdma mailing lists[1]. This series adds RDMA support to the ice driver for E810 devices and converts the i40e driver to use the auxiliary bus infrastructure for X722 devices. The PCI netdev drivers register auxiliary RDMA devices that will bind to auxiliary drivers registered by the new irdma module.
