Created an attachment (id=6169)

Proposed enhancement

This is the enhancement/fix I have tested and we are using.

The main change is an additional function to decode the QoS Info field.
Unfortunately the wireless standard is changes the meaning of the bit fields
depending on the direction of the frame (to/from Access Point).... To handle
this I have added an ftype function to several functions so that the decoode
logic knows what frame the field is contained in and can "do the right thing".
If the frame type is unexpected, or the decoder is called from another
protocol, the decode will fall back to just displaying the raw decimal value.
