An auxiliary device will be created if the hardware indicates support for RDMA. The bnxt_ulp_probe() function has been removed and a new bnxt_rdma_aux_device_add() function has been added. The bnxt_free_msix_vecs() and bnxt_req_msix_vecs() will now hold the RTNL lock when they call the bnxt_close_nic()and bnxt_open_nic() since the device close and open need to be protected under RTNL lock. The operations between the bnxt_en and bnxt_re will be protected using the en_ops_lock. This will be used by the bnxt_re driver in a follow-on patch to create ROCE interfaces.
