mainlining shenanigans

To make sense of the map index, the tracepoint user also need to know that map we are talking about. Supply the map pointer but only expose the map->id. The 'to_index' is renamed 'to_ifindex'. In the xdp_redirect_map case, this is the result of the devmap lookup. The map lookup key is exposed as map_index, which is needed to troubleshoot in case the lookup failed. The 'to_ifindex' is placed after 'err' to keep TP_STRUCT as common as possible. This also keeps the TP_STRUCT similar enough, that userspace can write a monitor program, that doesn't need to care about whether bpf_redirect or bpf_redirect_map were used.

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.
