The Mellanox ConnectX can operate as an InfiniBand adapter, as an Ethernet NIC, or as a Fibre Channel (FC) HBA. The kernel has a low-level driver, mlx4_core, which handles multiplexing access to the device, and there is also already an InfiniBad driver, mlx4_ib. This patch adds a new driver, mlx4_en, which implements a standard Ethernet NIC driver.
