forcedeth: call restore mac addr in nv_shutdown path
after | commit f735a2a1a4f2a0f5cd823ce323e82675990469e2 | Author: Tobias Diedrich <ranma+kernel@tdiedrich.de> | Date: Sun May 18 15:02:37 2008 +0200 | | [netdrvr] forcedeth: setup wake-on-lan before shutting down | | When hibernating in 'shutdown' mode, after saving the image the suspend hook | is not called again. | However, if the device is in promiscous mode, wake-on-lan will not work. | This adds a shutdown hook to setup wake-on-lan before the final shutdown. | | Signed-off-by: Tobias Diedrich <ranma+kernel@tdiedrich.de> | Signed-off-by: Jeff Garzik <jgarzik@redhat.com> my servers with nvidia ck804 and mcp55 will reverse mac address with kexec. it turns out that we need to restore the mac addr in nv_shutdown().
