This adds a check for the required add and delete functions up front at registration time to be sure both are defined. Since both the features check and the registration check are looking at the same things, break out the check for both to call. Lastly, for some reason the feature check was setting xfrmdev_ops to NULL if the NETIF_F_HW_ESP bit was missing, which would probably surprise the driver later if the driver turned its NETIF_F_HW_ESP bit back on. We shouldn't be messing with the driver's callback list, so we stop doing that with this patch.

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.
