AW: Bug: QCA9880 hw2.0: TX-Rate Display in Wireshark

Hi Michal,

thanks for your instant response.
May I ask why this isn't implemented in a new firmware release?
Is there a short manual, what and where I need to edit the code and how to compile it? I'm not that familiar with coding on that level.

Best Regards,

If you don't mind dirtying your hands with some C code you can try using the following patch (it will not cleanly apply to upstream kernel but should be fairly straightforward to port):!topic/chromium-os-checkins/YGYm6gNUnEE
