de2104x: fix power management
At least my 21041 cards come out of suspend with bus mastering disabled so they did not work after resume(no data transferred). After adding pci_set_master(), the driver oopsed immediately on resume - because de_clean_rings() is called on suspend but de_init_rings() call was missing in resume. Also disable link (reset SIA) before sleep (de4x5 does this too). Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Acked-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: David S.
