- Add some basic checks for i_fc* bits (ToDS, FromDS, MoreFrag, Protected);
those are used / checked across various places in Tx path.
- Mark injected 802.11 frame as encapsulated (just as it should be).
- Classify 802.11 frame in a proper way (extract ether_type from LLC header
for Data frames, use AC_BE queue for others (NoData / Management / Control).
- Subtract header length from tx_bytes statistics (so it will correspond
to the comment).
Was checked with RTL8188EU (AP) + Intel 6205 (STA).
