No, this is exactly the patch which causes the problem for you. The parameter
for these settings stayed the same but this patch changes the order in
ieee80211_rate to make it easier for the driver to parse the (reordered) rx
status information for CCK rates (maybe also tx - not sure about that right

What about broadcast? MGMT was only mentioned here because it is the third
item which can be manipulated the same way. But yes, it would be good to get
the mgmt rates in sync with the non-hw-rate-control drivers.
