I didn't do detailed review, but my general impression is very very
positive. New driver looks great!

Just 2 generic remarks:
- please add MAINTAINERS file entry
- please post a patch or request to remove staging/rtlwifi driver
  since this one is replace for it (8822BE PCI-ID is the same)

Thanks
Stanislaw
