[ Upstream commit a0dc02039a2ee54fb4ae400e0b755ed30e73e58c ] In ieee80211_rx_h_mesh_fwding, we increment the 'dropped_frames_ttl' counter when we decrement the ttl to zero. For unicast frames destined for other hosts, we stop processing the frame at that point. For multicast frames, we do not rebroadcast it in this case, but we do pass the frame up the stack to process it on this STA. That doesn't match the usual definition of "dropped," so don't count those as such. With this change, something like `ping6 -i0.2 ff02::1%mesh0` from a peer in a ttl=1 network no longer increments the counter rapidly.

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.
