I doubt that there is a qemu emulation for the TSECs...

Well, if you check the configuration you will see that it has a
plain

	# CONFIG_TSEC_ENET is not set

so the TSECs will indeed not work.  But then, there is

	CONFIG_E1000=y

It would have been helpful if you had included the actual boot
messages of your system.  There should be some E1000 network
interface visible...

Best regards,

You can do this in a number of ways.     IBM chose to do all of them.
