Yeah, I didn't mean bring over quite so literally.. Chris is studying
it and figuring out the neatest way to reimplement the required bits.

As for the relationship with bluetooth.. actually the bug that Chris
is working on here is that the rtl8xxxu wifi signal is totally
unusable *until* the bluetooth driver is loaded.
Once the bluetooth driver is loaded, at the point of bluetooth
firmware upload, the rtl8xxxu signal magiaclly strength becomes good.
I think this is consistent with other rtl8xxxu problem reports that we
saw lying around, although they had not been diagnosed in so much
The rtl8723bu vendor driver does not suffer this problem, it works
fine with or without the bluetooth driver in place.
