This patch updates the tc-bpf.8 example application for changes to the
struct bpf_elf_map definition. In it's current form, things compile, but
the resulting object file is rejected by the verifier when attempting to
load it through tc.

[ dropped the unnecessary flags initialization on commit ]
Update the list of architectures supporting eBPF JIT as of Linux 4.18.
Also mention the Linux version where support for a particular
architecture was introduced. Finally, reformat the list of architectures
as a bullet list in order to make it more readable.

Add a start of a man-page to the misc section as a reference and
guide on (e)BPF classifier and actions. Given that tc is only tersely
documented, this is provided in the hope that users will have an
easier getting started with tc and (e)BPF. And, that there's now more
incentive for others to also start documenting their classifier and
actions as well. ;)
