Description

This test is intended to test transfering data in promisc mode

How to test

create an 1G file in the host

dd if=/dev/urandom of=/tmp/random bs=1024k count=1000

get che checksum of the random file
```
md5sum /tmp/random
```
open a guest session and execute the following command to switch between promisc and non-promisc mode:
while true; do

ifconfig eth0 promisc

sleep 0.01

ifconfig eth0 -promisc

sleep 0.01

done
in the meantime, scp the random file to the guest
```
scp /tmp/random root@guest_ip:/tmp
```
compare the md5sum for both guest and host
kill the previous script in the guest
restore the nic to non-promisc mode
```
ifconfig eth0 -promisc
```

compare the md5sum for both guest and host, if they are different, fail the whole testcase
