PATCH (RESENT) swsuspend for ne2k-pci cards

[Éric Brunet]

Hi,

This is a resent of my patch to add suspend/resume support to ne2k-pci
network adapters.

* The patch was tested on a RealTek ne2k clone and works nicely,
* It was reviewed and largely improved by Arkadiusz Miskiewicz
* It was approved of by Pavel Machek, the software suspend maintainer.

It would be nice if this patch could go into the kernel.

Thank you,

	Éric Brunet
