Hi Gavin,
The shutdown handler implementation was recently merged into net-next.

Can you try these 2 patches from net-next? 

commit 4c305fa2cbe2a85c34899763fcefb843c87b591d
Author: Nithin Sujir <nsujir@...adcom.com>
Date:   Mon Jul 29 13:58:37 2013 -0700

    tg3: Implement the shutdown handler

    Also remove the call to tg3_power_down_prepare() in tg3_power_down()
    since tg3_close() calls it.

commit 5137a2ee2007d9cbbbeebd14abe08357a079b607
Author: Nithin Sujir <nsujir@...adcom.com>
Date:   Mon Jul 29 13:58:36 2013 -0700

    tg3: Allow NVRAM programming when interface is down


Thanks,
Nithin.
