So.. how much of this is still from mabbas now?

Only the second case actually works with this code.
When a frame is being transmitted, the rate control runs this little bit of
code (rc80211_simple.c, line 255):
if (sdata->bss && sdata->bss->force_unicast_rateidx > -1)
sta->txrate = sdata->bss->force_unicast_rateidx;
This means:
1. If force_unicast_rateidx is set to 0 or higher, the tx rate will be fixed
to just that one rate, and..
2. sta->txrate is automatically set from force_unicast_rateidx as necessary.
