rtl8187: make CTS-to-self protection work
CTS protection was not working properly because the HW needs RTS flag to be asserted, and it need also RTS duration field to be filled with CTS-to-self duration. This patch makes the driver to do this. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
