Many types of network interface hardware require the use of a link layer protocol address. In the case of Ethernet, this address is sometimes known as the hardware address or MAC address. In some applications, it may be desirable to get the current configured hardware address for a specific interface. This may be performed by calling NetIF_AddrHW_Get() with the appropriate arguments.
Setting MAC Address
Some applications prefer to configure the hardware device’s hardware address via software during run-time as opposed to a run-time auto-loading EEPROM as is common for many Ethernet devices. If the application is to set or change the hardware address during run-time, this may be performed by calling NetIF_AddrHW_Set() with the appropriate arguments. Alternatively, the hardware address may be statically configured via the device configuration structure and later changed during run-time.
Note: In order to set the hardware address for a particular interface, it must first be stopped. The hardware address may then be set, and the interface re-started.
