sr() function is for sending packets and receiving answers. The function #returns a couple of packet and answers, and the unanswered packets.
sr1() is a variant that only return one packet that answered the packet (or #the packet set) sent. The packets must be layer 3 packets (IP, ARP, etc.).
srp() do the same for layer 2 packets (Ethernet, 802.3, etc.).
