Setting legacy bit-rates no longer works?

Setting legacy bit-rates no longer works?

[Ben Greear]

I tried this on a 3.17.0-rc7+ kernel, but reported tx-rate stays at 54Mbps

iw dev sta1 set bitrates legacy-5 24

Driver is ath9k, but wpa_supplicant is configured to disable HT.

I'm going to go dig into this, but if someone has any suggestions,
please let me know.

Thanks,
Ben

Ok, so my problem is that I was trying to set legacy-2.4 rates with one call to iw,
and legacy-5 rates with another.  Any non-specified rates get set to full bit-rate,
so that is why it wasn't working.

You have to do something like:

iw dev sta1 set bitrates legacy-2.4 24 legacy-5 24

Probably any time supplicant sets the rates, even if not specifying
legacy, it is going to over-write your previously set legacy rates.

I think the kernel should just not make any changes if the user does
not specify that entry in the netlink message, but that is a problem
for another day.

Thanks,
Ben
