Sorry, I don't follow that train of thought. Due to the lack of numbers 
comparing the magic formula (tx /3) with actual throughput we (Antonio and I) 
ran a few tests on ath10k devices using your patch. Surprising to us, this 
approach worked quite well. 

I will re-post your patch as RFC to encourage others to test the resulting 
B.A.T.M.A.N. V routing decisions. If you happen to have tested more on your 
end, please share your results.

Also, why considering rx on top of tx still isn't clear. Could you explain 
some more ?

Thanks,
Marek
