Discussion of patch upstream:
https://lkml.org/lkml/2013/1/5/81
The patch was cc'd to stable, so it will make it's way into the Ubuntu
kernels through the usual stable update process. It just needs to make
it into Linus' tree first, then down through upstream stable.

Bug description:
Testing saucy iscsi target booted on e500mc default initrd hangs
when tg3 driver started.
saucy was installed to an iSCSI target using the interactive setup from:
http://ports.ubuntu.com/dists/saucy/main/installer-powerpc/current/images/e500mc/netboot/vmlinux
http://ports.ubuntu.com/dists/saucy/main/installer-powerpc/current/images/e500mc/netboot/initrd.gz
Linux version 3.11.0-5-powerpc-e500mc
initrd.img-3.11.0-5-powerpc-e500mc
Booted from flash USB to simulate a pxe boot.

IP-Config: no response after 10 secs - giving up
-> System is alive ( I have a prompt ) - The above SHOULD HAVE
WORKED since it is an active port.
