Bad rtwn(0) performance with RTL8188CE on -CURRENT after r302035

Hi,

thanks to previous efforts, the rtwn(0) connection for my RTL8188CE
wireless card is far more stable. It seems to come at the price of
relatively bad performance, though. After r302035 from avos_at_, I
can't get more than 500 kbit/s downstream from anywhere.

Let me know, what information is necessary to isolate and correct
that issue. I'll gladly test it. :-)

Cheers
Marcus
