like other PCI network drivers. The sys/ofed directory is now mainly reserved for generic infiniband code, with exception of the mthca driver. - Add new manual page, mlx4en(4), describing how to configure and load mlx4en. - All relevant driver C-files are now prefixed mlx4, mlx4_en and mlx4_ib respectivly to avoid object filename collisions when compiling the kernel. This also fixes an issue with proper dependency file generation for the C-files in question. - Device mlxen is now device mlx4en and depends on device mlx4, see mlx4en(4). Only the network device name remains unchanged. - The mlx4 and mlx4en modules are now built by default on i386 and amd64 targets. Only building the mlx4ib module depends on WITH_OFED=YES .
