 In both XO1.0 and 1.5 the Tx excessive retries counter on the iwconfig is
 not being reset. This behavior impacts in the way the Quality is computed
 in the iwconfig since ic calculated by SNR and by retries and then the
 biggest one is dropped. Luckily the Quality is defined as U32 so the
 negative values reached in the Quality by retries turns into gargantuan
 positives and then they are dropped.
 The counter doesn't resets even if you connect to a new AP, the only way
 for resetting is rebooting.
 I tried this both on F9 and F11 builds and is the same except because of
 the speed in which increases the counter. The mesh traffic seams to
 increase the counter much faster due to the mesh traffic.

 Bye and for any question don't hesitate in asking
