The WEXT ioctl SIOCSIWRATE is not implemented in mac80211. This patch
adds the missing routine. It supports the 'auto' keyword, fixed rates,
and the combination of 'auto' and a fixed rate to select an upper bound.

I'm working on getting his name.

No. max_ratectrl_rateidx and force_unicast_rateidx can do everything you need.
Look more carefully at how the rate control code works with those two fields.
The only file that needs to be patched to add support for this is
ieee80211_ioctl.c because this feature was always supported. (with
non-standard prism2/hostap ioctls)
I think I understand now. I could see how the two existing variables can be used for the maximum
rate, but not for the range of rates implied when the 'auto' keyword of the iwconfig command is
used. Now I see that sta->supp_rates and sdata->u.sta.supp_rates_bits can be used for the necessary
bitmaps. I was reluctant to destroy them, but now I see that they will be rebuilt with later calls
to iwconfig.
I am testing the new version and will be sending it along later.
