Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

The figure in section 7.1.2 suggests a body size of up to 2312
bytes is allowed, which is a bit confusing, I suspect this
represents the 2304 bytes of real data, plus a possible 8 bytes of
WEP IV and ICV. (this interpretation suggested by Ramiro Barreiro) */
