18 * This is "two-way" interface, acting as the SHIM layer between WL and PHY layer.
19 * WL driver can optinally call this translation layer to do some preprocessing, then reach PHY.
20 * On the PHY->WL driver direction, all calls go through this layer since PHY doesn't have the
21 * access to wlc_hw pointer.
