Auto TX rate adaption

[Olof Johansson]

Thanks for the reply!

However, I'm a bit confused :)

In the tx_bd struct there is a bd_rate:2 bit field. Is this the
data_rate index you mean?

Could you explain what the possible values here does, 0, 1, 2?

>From what I can tell, there is no field in the tx_db struct thats
contains the rate, but I haven't looked at the dumps here so I might
be wrong?

Where can the firmware pick rates from? BD and TPE? What are these and
how do I set them? Where does the firmware get it's rate values? I
guess they must match something in the nv-file?

I know these are basic questions, but other wlan hw I've worked with
has had quite straightforward ways of enabling the autorate and fixing
rates if required. So I'm a bit stumped... :)

Cheers
