18 * $Date: 24. January 2020
21 * Project: Ethernet PHY (Physical Transceiver) Driver definitions
26 * Removed volatile from ARM_ETH_LINK_INFO
28 * ARM_ETH_LINK_INFO made volatile
30 * changed parameter "mode" in function ARM_ETH_PHY_SetMode
31 * Changed prefix ARM_DRV -> ARM_DRIVER
32 * Changed return values of some functions to int32_t
34 * Namespace prefix ARM_ added
