rtlwifi: rtl_pci: Start modification for new drivers
Future patches will move the drivers for RTL8192EE and RTL8821AE from staging to the regular wireless tree. Here, the necessary features are added to the PCI driver. Other files are touched due to changes in the various data structs. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
