We cannot make a direct call to nf_ip6_checksum_partial() because that would result in autoloading the 'ipv6' module because of symbol dependencies. Therefore, define checksum_partial indirection in nf_ipv6_ops where this really belongs to. For IPv4, we can indeed make a direct function call, which is faster, given IPv4 is built-in in the networking code by default. Still, CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline stub for IPv4 in such case. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
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.
