Considering there is a driver for RTL8188EU already in staging,
which people have been whittling down, should I put any effort
into adding support to rtl8xxxu?
It's actually mostly working already [0], but rtl8xxxu doesn't
have AP mode, adhoc mode, power saving, etc so it wouldn't be
necessarily better than the driver in staging.

The staging driver is based on the vendor driver which is rather
dreadful. Given the similarity of the chips, it feels really silly to
have a second driver for just one chip.
I see no reason to abandon 8188eu support in rtl8xxxu, but given my
total lack of time, I am also not able to invest in it.
Cheers,
Jes

So now I actually tested r8188eu and it's so bad. Why are people
spending so much time cleaning up a driver that doesn't work well?
With the default module parameters it had 35% packet loss with the
router 3 meters away in the same room. With rtw_power_mgnt=0 the
packet loss is gone but the speed is still disappointing: less than
50 megabits/second download, 65-70 upload, and it's unsteady.
The v5.2.2.4 driver from Larry Finger's repo works much better:
no packet loss and a steady 95 and 85 megabits/second in the same
conditions.
I'll get started then.
