From memory I think I had a lot of reported TX error with 3.9.9 and
they are now gone with 3.10 but the number of misc error reported by
iwconfig is still high with 3.10. But you are right the fix for TX is
still in wireless git and does not seem to be in 3.10. As I checked
several git trees I mist have been confused...

OK. Next radical solution is to open the laptop and change for another
half mini pcie card... Quite difficult to find one reliably even if
there are some available on ebay.
Thanks for taking the time to respond...
