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