Add the PCI write end padding flag to device_cap_flags enum and set it during mlx5_ib_query_device so it will be reported to user-space. During WQ/QP creation, set that capability for WQ/QP if user requested it and HW supports it. PCI write end padding modification is not supported for now. There's no such flag for a QP but for a WQ, create and modify use the same flag. Return an error if PCI write end padding flag is set during modify_wq.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
