This protocol operates in the IP layer and provides data communication. IP
fragmentation is not supported. It is not possible to receive the fragmented packets. All
protocol number is supported except for TCP or UDP. In case of TCP or UDP, use the
hardwired embedded TCPIP stack.
ICMP is a protocol which provides information, unreachable destination. When a Ping-
request ICMP packet is received, a Ping-reply ICMP packet is sent.
This protocol processes IGMP messages such as the IGMP Join/Leave. The IGMP is only
enabled in UDP multicast mode. Only version 1 and 2 of IGMP logic is supported. When
using a newer version of IGMP, IGMP should be manually implemented in the IP layer.
It is a protocol which supports data communication at the UDP layer. User datagram
such as unicast, multicast, and broadcast are supported
This protocol operates in the TCP layer and provides data communication. Both TCP
server and client modes are supported.
