[Testing] some errors on iwconfig

[Ronak Chokshi]

We have talked about populating link quality field with different sorts
of values but we haven't gotten a consensus on that yet. I will dig up
the latest email threads on that topic but suggestions are definitely
welcome. Link quality in a mesh network usually doesn't hold too much of
sense because there are several links to neighbor mesh nodes to start
with. So, there is not one RF link that can be justified as a candidate
for calculating link quality.

 

Thanks

Ronak

I assume that you are using an XO. 
What OS build does it run? 

I am not sure how link quality is calculated and I never pay too much
attention to it. 
Points 2,3 and 4 are normal

always got below errors:

eth0      MRVL-USB8388  ESSID:"zxc555"  Nickname:"zxc55555"
          Mode:Managed  Frequency:2.412 GHz  Access Point:

1. link quality alway 100% which is impossible
2. Rx invalid frag: always happen
3.  Tx excessive retries: always high
4. Invalid misc: alway increasing in numbers.
