2018-05-14bpf, doc: convert bpf_design_QA.rst to use RST formattingJesper Dangaard Brouer1-79/+144
The RST formatting is done such that that when rendered or converted to different formats, an automatic index with links are created to the subsections. Thus, the questions are created as sections (or subsections), in-order to get the wanted auto-generated FAQ/QA index. Special thanks to Quentin Monnet <quentin.monnet@netronome.com> who have reviewed and corrected both RST formatting and GitHub rendering issues in this file. Those commits have been squashed. I've manually tested that this also renders nicely if included as part of the kernel 'make htmldocs'. As the end-goal is for this to become more integrated with kernel-doc project/movement.

2018-05-14bpf, doc: rename txt files to rst filesJesper Dangaard Brouer1-0/+156
This will cause them to get auto rendered, e.g. when viewing them on GitHub. Followup patches will correct the content to be RST compliant. Also adjust README.rst to point to the renamed files.
