The Hardware Drivers subproject is a collection of different multi-vendor  HCA drivers to support their own HCA products. The specification published in HCA Driver DDK permits multi-vendor implementations to co-exist in a system. The vendor may choose to provide a  kernel mode driver to interface with the Access Layer in kernel mode. In addition if the HCA implementation permits direct OS bypass method to perform direct IO with the hardware, then the vendor will also provide a user mode library to interface with the user mode Access Layer.
