Description

After teaching some classes about Scapy, I found that students were quite confused by the naming convention of send and receive functions (and sometimes, I am confused too :). For example, sendp() is used to send *packets* at layer2. This is confusing because usually frames are sent at layer2.

I will suggest to add new names to ease remembering which function does what such as: sr1l2 = send and receive one *packet* at layer 2 sr1l3 = send and receve one packet at layer 3 sendl2 = send one *packet* at layer 2 sendl3 = send one packet at layer3 and so on ...
