Intel I350 mini-PCIe card (igb) on Mirabox (mvebu / Armada 370)

[matthew_minter@xyratex.com (Matthew Minter)]

Just to confirm, this patch is stopping my kernel panic also, I am
still suffering from another minor issue however this does seem to be
the crux of my problem also. I can however happily say that I regard
my hotplug issue closed.

Many thanks guys
