You can refer to the below stated example applications for more details which gives an idea of how the EmacLite and its driver/examples are intended to be used.

SYSTEM REQUIREMENTS: The system containing the EmacLite should have the following capabilities:

Processor based system
At least one EmacLite core
An interrupt controller
An external memory controller with at least 200KB of RAM available
A UART to display messages

xemaclite_example.h

This headerfile defines common data types, prototypes, and includes the proper headers for use with the EmacLite examples. This file needs to be used with xemaclite_phy_loopback_example, xemaclite_polled_example, xemaclite_intr_example and xemaclite_internal_loopback_example.c

For details, see xemaclite_example.h.

xemaclite_example_util.c

Contains an example on how to use the XEmaclite driver directly. This example implements the utility functions for the EmacLite example code. This file needs to be included in xemaclite_phy_loopback_example, xemaclite_polled_example, xemaclite_intr_example and xemaclite_internal_loopback_example.c

For details, see xemaclite_example_util.c.

xemaclite_internal_loopback_example.c

Contains an example on how to use the XEmaclite driver directly. This is an interrupt example outlining the use of interrupts and callbacks in the transmission/reception of Ethernet frames using internal loop back with an incrementing payload from 1 byte to 1500 bytes (excluding Ethernet Header and FCS).

For details, see xemaclite_internal_loopback_example.c.

xemaclite_intr_example.c

Contains an example on how to use the XEmaclite driver directly. This is an interrupt example outlining the use of interrupts and callbacks in the transmission/reception of an Ethernet frame of 1000 bytes of payload.

For details, see xemaclite_intr_example.c.

xemaclite_phy_loopback_example.c

Contains an example on how to use the XEmaclite driver directly. This is an interrupt example outlining the use of interrupts and callbacks in the transmission/reception of Ethernet frames using MAC loop back in the PHY device with an incrementing payload from 1 byte to 1500 bytes (excluding Ethernet Header and FCS). This example can be run only when the MDIO interface is configured in the EmacLite core.

For details, see xemaclite_phy_loopback_example.c.

xemaclite_ping_reply_example.c

Contains an example on how to use the XEmaclite driver directly. This is an EmacLite ping reply example in polled mode. This example will generate a ping reply when it receives a ping request packet from the external world.

For details, see xemaclite_ping_reply_example.c.

xemaclite_ping_req_example.c

Contains an example on how to use the XEmaclite driver directly. This is an EmacLite Ping request example in polled mode. This example will generate a ping request for the specified IP address.

For details, see xemaclite_ping_req_example.c.

xemaclite_polled_example.c

Contains an example on how to use the XEmaclite driver directly. This is an polled mode example outlining the transmission/reception of an Ethernet frame of 1000 bytes of payload.

For details, see xemaclite_polled_example.c.

xemaclite_selftest_example.c

Contains an example on how to use the XEmaclite driver directly. This example performs the basic selftest using the emaclite driver.

For details, see xemaclite_selftest_example.c.

EXAMPLES IN EDK/SDK:

Each example is independent from the others except for common code found in xemaclite_example_util.c. When including source code files in an EDK/SDK SW application, select xemaclite_example_util.c along with one other example source code file.
