This line of code serialized the python structure for the device and throws it at the log file. The string is about 90K characters, isn't very useful and we found that it takes a very large amount of space in the log file causing them to grow very quickly and fill our log disk. This change extracts the device name (e.g. "tapcdc07af9-8a") and uses that in the log message. Change-Id: I240eb811445752407583f0fb322ce061acb293b9 Fixes: Bug #1200321
