I am not sure about how to create corrupted packets. Normally you should 
get lot of corrupted packets from surrounding transmission. In my case, 
monitor mode hangs sometime and I don't get any packets. Then if I 
delete the interface and create a new interface using the iw command I 
gave earlier, I get packets with crc error. You can also modify already 
created interface using

iw wlan0 set monitor flag fcsfail
