This reverts commit fd48124e09 ("staging: r8188eu: simplify
rtw_get_ff_hwaddr").
The cleanup in this commit removes the qsel to addr mappings in
rtw_get_ff_hwaddr. The underlying assumption is that rtw_write_port
uses its addr parameter only for the high_queue check.
This is obviously incorrect as rtw_write_port calls
ffaddr2pipehdl(pdvobj, addr);
where addr is mapped to a usb bulk endpoint.
Unfortunately, testing did not show any problems. The Edimax V2 on which I
tested has two bulk out endpoints. I guess that with the incorrect patch,
addr could only be 0 (no high queue) or 6 (high queue), both of which were
mapped to the first bulk out endpoint. Data transfers did still work...
