skb_crc32c_csum_help is like skb_checksum_help, but it is designed for checksumming SCTP packets using crc32c (see RFC3309), provided that libcrc32c.ko has been loaded before. In case libcrc32c is not loaded, invoking skb_crc32c_csum_help on a skb results in one the following printouts: warn_crc32c_csum_update: attempt to compute crc32c without libcrc32c.ko warn_crc32c_csum_combine: attempt to compute crc32c without libcrc32c.ko Signed-off-by: Davide Caratti <dcaratti@redhat.com> Signed-off-by: David S.

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.
