[patch 18/43] mv643xx_eth_pcidev: implement hotplug for the marvell gige functionality by probing the northbridge pci id

[akpm@osdl.org]

From: Sven Luther <sl@bplan-gmbh.de>

Add Marvell gigabit ethernet hotplug through the northbridge pci id support
for the Pegasos machines.

This patch is not optimal, as the proper way to handling this is to bring
full hotplug support to the platform drivers, but this would be much more
invasive and far reaching a project.  This approach matches the marvell
discovery northbridge pci id to load the driver for the builtin gigabit
ethernet function, and is similar of what is done already using the
discover module loading technique.  With more and more distributions moving
to using hotplug only to probe for modules to load, this patch becomes
necessary.
