Hello, This series extends the behavior of the SIOCGMIIREG and SIOCSMIIREG IOCTLs to use the convenience functions mmd_phy_read() and mmd_phy_write() for C45 access. This brings the benefit of the core falling back to indirect C22 access of the underlying driver do not itself provide C45 read/write capability. Patch 1/2 exposes the read/write functions making them available to the IOCTL callback. While patch 2/2 changes the IOCTL callback to make use of them. Without this change using tools like phytool to read/write registers on a C45 only PHY using a C22 only driver fails as the IOCTL callback don't know how to talk C45 on the mdio bus.
