PATCH swsuspend for ne2k-pci cards

[Éric Brunet]

Hi,

Arkadiusz Miskiewicz had some suggestions to improve my patch which
adds suspend/resume support to ne2k-pci.c. Actually, he basically rewrote
it.

This patch was only tested on my own ne2k clone [Realtek Semiconductor
Co., Ltd. RTL-8029(AS)], and it works nicely for me. As 1) it cannot hurt
people which are not using swsuspend 2) it can only improve things for
people using swsuspend, it would be nice if this patch could go into the
kernel.

Thank you,

	Éric Brunet
