Expect command is suitable > for unit test and regression test by saving batch expect scripts into a > file and use 'load' command to invoke them together. > 3. pktgen - new testpmd forwarding engine > Used to support tx, rx and expect blocking command. > Also support rxonly/loopback/forward/macswap non-blocking idle modes > with several packet dump choice. > 4. py command - new testpmd CLI > Run and evaluate python clause in a global context, samples: > - py a = 123; b=0xaaa; hex(a+b) > - py eth=Ether();ip=IP(); > - py hexdump(eth/ip/UDP()); > - tx 0 eth/ip > py shell: sneak into python shell > > The purpose of this scapy/python integration is to help programmers to > speed up unit test w/o writing complex c code, verify features with batch > expect scripts.
