21 * Project: Ethernet MAC (Media Access Control) Driver definitions
26 * Added ARM_ETH_MAC_SLEEP Control
28 * Changed MAC Address handling:
29 * moved from ARM_ETH_MAC_Initialize
30 * to new functions ARM_ETH_MAC_GetMacAddress and ARM_ETH_MAC_SetMacAddress
31 * Replaced ARM_ETH_MAC_SetMulticastAddr function with ARM_ETH_MAC_SetAddressFilter
32 * Extended ARM_ETH_MAC_SendFrame function with flags
33 * Added ARM_ETH_MAC_Control function:
34 * more control options (Broadcast, Multicast, Checksum offload, VLAN, ...)
35 * replaces ARM_ETH_MAC_SetMode
36 * replaces ARM_ETH_MAC_EnableTx, ARM_ETH_MAC_EnableRx
37 * Added optional event on transmitted frame
38 * Added support for PTP (Precision Time Protocol) through new functions:
39 * ARM_ETH_MAC_ControlTimer
40 * ARM_ETH_MAC_GetRxFrameTime
41 * ARM_ETH_MAC_GetTxFrameTime
42 * Changed prefix ARM_DRV -> ARM_DRIVER
43 * Changed return values of some functions to int32_t
45 * Name space prefix ARM_ added
47 * Renamed capabilities items for checksum offload
