TX statistics

Hello again,

I'm still trying to calculate the Packet Delivery Ratio statistic.

By considering the tx_packets variable which represents the packets
passed to ath10k driver for transmission, I thought I should be able
to calculate the probability of successful transmission by disabling

However iw set retry does not seem to work and I have neither found a
way to do it through a hack in ath10k source code.

Can you please provide me with a direction on how to do that?

Thank you in advance,
