Move dissection of tunnel info to outside of the main flow dissection function, __skb_flow_dissect(). The sole user of this feature, the flower classifier, is updated to call tunnel info dissection directly, using skb_flow_dissect_tunnel_info(). This results in a slightly less complex implementation of __skb_flow_dissect(), in particular removing logic from that call path which is not used by the majority of users. The expense of this is borne by the flower classifier which now has to make an extra call for tunnel info dissection. This patch should not result in any behavioural change.

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.
