hi!

I've pushed a bunch more changes / fixes into rtwn. This includes a bunch
of RTL8192CU fixes and preparation for firmware rate control support.

One of the changes removes an old work-around. I've tested it locally on my
11bg and 11bgn APs in 11b, 11g and 11n modes. It seemed to behave just fine
now that I've fixed other parts of the driver. But 802.11 is unpredictable
at the best of times, and it's possible I haven't been in enough weird wifi
environments lately!

So if you're using rtwn, please do update to the latest -HEAD and try it
out and report back. If you're using or have an RTL8192CU USB NIC, I would
super appreciate any feedback about behavioural changes.

Thanks!
