Rate Changing Algorithm file for RT-AC3200?

[holyhexor]

I am working on a project for a grad course. I could successfully compile the firmware for my RT-AC3200, but I am finding it hard to figure out which rate changing algorithm and which file in particular is being executed. Also, many files were not compiled at all. For example, I run the "make RC3200" command from the directory

asuswrt-merlin/release/src-rt-7.x.main/src/linux/linux-2.6.36/net/mac80211/

After successfully compiling the firmware, object files are not created for any of the files in the same directory. Am missing something important? Any reply is much appreciated.

Can you explain what you mean by "rate changing algorithm".

Also, some of the components are only available pre-compiled binaries, like the wireless drivers.

EDIT: I guess you're referring to this, which is way beyond my ability to understand. Good luck.

Thanks for your reply. I am aware that the software related to Broadcom chipset is proprietary.
Rate changing algorithms that increase/decrease the transmission rate. Algorithms like Minstel, Minstrel-HT, etc. You can see in the picture that some files containing these algorithms exist, but none of these files are actually compiled.

You cannot run make outside of where it's meant to be run (within the Broadcom SDK directory).

Those files are not compiled because they're not enabled in the kernel config, as they are not used by the Broadcom proprietary drivers. This stack only work for a specific list of open-source wireless drivers.

Thank you for the reply, RMerlin.
My bad. Just checked that I run make from asuswrt-merlin/release/src-rt-7.x.main/src/. Could you tell me where I can change the rate adaptation algorithm?

You can't. Wireless driver is closed source.

You can't. Wireless driver is closed source.

Sorry for these retarded questions, but is there any possibility to manually change one configuration after the other? I basically want to find the frame error rate for all configurations

Same answer, sorry. Proprietary, closed source driver. Without a licence that gives you access to Broadcom's SDK, you can't do anything with it.

If you need access to low-level data, you will have to use a wireless device that comes with open-source drivers.

Alright. Appreciate your help.
