Thanks Pavel Roskin.

I have few more doubts.

The function  , "__ieee80211_data_to_8023()" , is called in
ieee80211_rx_h_data without any conditional check.

What parameters decides the frame conversion ?

Also, direct conversion between TID field in 802.11 to COS field in 802.3 .
I guess that its a direct memcpy of that filed based on frame control field
information. Is this correct ?

Any clues will be of great help.
