Packet Sniffer

Program sniffs packet from the given interface. Interface was given by the user as an argument of the program "-i", if an interface wasn't given then the program prints available interfaces, their name, ip adress and broadcast adress.

Extensions

Program processes also ICMP packets and accepts two additional arguments -c and -icmp, which are used to display just ICMP packets.
