1.1. samples/net/sockets/big_http_download with qemu_x86. Setup per http://docs.zephyrproject.org/subsystems/networking/qemu_setup.html (including http://docs.zephyrproject.org/subsystems/networking/qemu_setup.html#setting-up-zephyr-and-nat-masquerading-on-qemu-host-to-access-internet). Make sure that the entire file is downloaded. Then make sure it's downloaded 3 times (total xfer: ~20MB). Ideally, larger total xfer should be tested, but as it is slow, that takes a lot of time. 1.2. samples/net/sockets/big_http_download with frdm_k64f/Ethernet. The testing is per above. (Keep in mind that loop-slip-tap.sh and friends should be stopped, but NAT/DNS setup is still required.
