[Make-wifi-fast] Mapping the mac80211 TX path

[Toke Høiland-Jørgensen]

Hi everyone

I've been trying to wrap my head around how the Linux mac80211 stack
actually works. As part of this, I've been drawing flow diagrams of the
code paths. The first one I completed is of the TX path; URL below in
case anyone else finds it useful. And if anyone discovers glaring (or
not) errors, feel free to point them out, of course :)
