=================================
The IPv4 Multicast application is a simple example of packet processing
-using the Intel® Data Plane Development Kit (Intel® DPDK).
+using the Data Plane Development Kit (DPDK).
The application performs L3 multicasting.

Explanation
.. code-block:: c
- /* construct destination ethernet address */
+ /* construct destination Ethernet address */
dst_eth_addr = ETHER_ADDR_FOR_IPV4_MCAST(dest_addr);
Since Ethernet addresses are also part of the multicast process, each outgoing packet carries the same destination Ethernet address.
-The destination Ethernet address is constructed from the lower 23 bits of the multicast group ORed
+The destination Ethernet address is constructed from the lower 23 bits of the multicast group OR-ed
with the Ethernet address 01:00:5e:00:00:00, as per RFC 1112:
