Access to PHY and radio registers is indirect on Broadcom hardware and it seems that addressing on some MIPS SoCs may require flushing. So far this problem was noticed on 0x4716 SoC only (marketing names: BCM4717, BCM4718). Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
